Description

Driving handle for prostate binding device Technical Field The invention relates to a driving handle for a prostate bundle nail, and belongs to the technical field of medical appliances. Background The prostate gland has increased throughout the life of men. In some men, the prostate capsule surrounding the prostate may prevent the prostate from further enlargement. This can cause the inner region of the prostate to squeeze the urethra. This pressure on the urethra increases the resistance to urine flow through the region of the urethra surrounded by the prostate. The existing treatment method can implant a prostate bundle nail into the urethra of the blocked prostate section of a patient through the natural cavity of the urethra, the prostate bundle nail can be nailed to the hypertrophied prostate tissue from the urethra like a stapler, the special structure can tighten the prostate tissue, the prostate can be bound by the cooperation of a plurality of nails (namely the bundle nails), the urethra can be expanded, and the prostatic gland body which is proliferated at the urethra part can be tightened by the bundle nails under the condition that the tissue is not resected, so that the compression of the gland body to the urethra is relieved, and the smoothness of the urethra is recovered. The existing treatment tool in the prior art comprises a module and a handle configured to accommodate the module, the handle and the module are combined to push the binding nails to carry out prostate binding nail operation, energy storage is needed to be carried out through the handle in advance when the binding nails are driven into prostate tissues so as to provide kinetic energy for driving the binding nails, the handle in the prior art normally stores energy when in production, a doctor can directly excite the handle during operation, because the puncture needle needs to be stretched into a prostate channel to find the alignment position firstly, at the moment, the problem of false excitation can occur because the driving handle stores energy well in advance, and operation errors are caused, so that the treatment tool has dangerousness. Disclosure of Invention The invention aims to provide a driving handle for a prostate bundle nail, which solves the problems of easy false excitation, surgical operation error and the like in the prior art. The technical aim of the invention is mainly achieved through the following technical scheme that the driving handle for the prostate bundle nail comprises an upper shell and a lower shell which are connected and matched with each other, a holding part is arranged on the side edge of the lower shell, a trigger is arranged on the adjacent side of the holding part, the trigger comprises a transmission section extending into the lower shell and a driving section which is positioned outside the lower shell and is positioned on the adjacent side of the holding part, a wheel disc for driving the bundle nail into prostate tissues is arranged in the lower shell, the end part of the transmission section is rotationally connected with the lower shell and can drive the wheel disc to intermittently rotate, a first transmission rack which is used for exciting the puncture needle and can move towards the position of the trigger is arranged in the lower shell, when the trigger moves towards the holding part, the driving section can drive the first transmission rack to move towards the position of the transmission section, the trigger is connected to the lower shell through the transmission section and can rotate so as to drive the wheel disc to rotate along with the trigger, the wheel disc can drive the bundle nail into the prostate tissues step by step, the driving section of the trigger can synchronously drive the first transmission section to move, and the first transmission rack can be enabled to be driven to move towards the position of the prostate tissues through multiple rotations, and the first transmission rack can be prevented from being driven to move towards the position of the transmission section and the position of the transmission section to be in the position of the transmission section to be matched with the position of the transmission of the drive needle when the puncture needle is safe and the operation is guaranteed to be safe and safe to realize to avoid to realize the operation. Preferably, a first gear meshed with the first transmission rack and capable of horizontally rotating is arranged in the lower shell, a second transmission rack which is in transmission connection with the driving section and meshed with the first gear is arranged on one side, opposite to the first transmission rack, of the first gear, the second transmission rack can be driven by the driving section, the second transmission rack drives the first gear and drives the first transmission rack to move through the first gear, and the stable transmission effect on the trigger and the first transmission r
