Description

Hemostatic forceps for thyroid surgery Technical Field The invention relates to the technical field of surgical instruments, in particular to a hemostatic forceps for thyroid surgery. Background Thyroid gland is a butterfly endocrine gland located in front of neck and right in front of trachea, and thyroid surgery, also called thyroidectomy, is a surgical operation with the aim of completely or partially resecting thyroid gland. Hemostat for thyroid surgery is a fine surgical instrument specially used for clamping, squeezing or temporarily blocking thyroid and surrounding rich blood vessels in thyroidectomy. In the use process of the existing hemostatic forceps, the inside of the finger ring is smooth, and when blood and tissue fluid infiltrate the instrument, an operator can easily slip when wearing sterile gloves to hold, so that the instrument is insufficient in holding stability, and potential safety hazards exist. Disclosure of Invention The invention aims to provide a hemostatic forceps for thyroid surgery, which aims to solve the problems of the background technology. The hemostatic forceps for thyroid surgery comprise a first forceps handle, a positioning pin and a second forceps handle, wherein the middle part of the first forceps handle is fixedly connected with the positioning pin, the outer wall of the positioning pin is rotationally connected with the second forceps handle, one side of the outer wall of the first forceps handle is connected with a first forceps head, the other side of the outer wall of the first forceps handle is connected with a first ring, one side of the outer wall of the second forceps handle is connected with a second forceps head, the other side of the outer wall of the second forceps handle is connected with a second ring, one side of the outer wall of the first ring is fixedly connected with a first lock catch, one side of the outer wall of the second ring is fixedly connected with a second lock catch, the inner wall of the first ring is connected with a first protruding part, the inner wall of the second ring is connected with a second protruding part, and the outer walls of the first protruding part and the second protruding part are provided with anti-sliding grooves; The first bulge is used for assisting the ring finger to push up the first forceps handle, the second bulge is used for assisting the thumb to push down the second forceps handle, and the anti-slip groove is used for increasing friction force between the finger and the hemostatic forceps. Preferably, the first protruding portion and the second protruding portion are arc-shaped, the first lock catch and the second lock catch are matched to form a ratchet structure, and one side of the outer walls of the first clamp head and the second clamp head is a toothed area. The ring finger increases friction force through the anti-slip groove of the outer wall of the first bulge part when the ring finger is arranged in the ring finger, and increases friction force through the anti-slip groove of the outer wall of the second bulge part when the thumb is arranged in the ring finger, so that slipping is prevented. Preferably, an integrated structure is formed between the first clamp handle, the first clamp head and the first ring, and an integrated structure is formed between the second clamp handle, the second clamp head and the second ring. The first finger ring moves to drive the first clamp handle to move together with the first lock catch, the second finger ring moves to drive the second clamp handle to move together with the second lock catch, the first clamp handle and the second clamp handle rotate with the locating pin as an axle center at the moment, and the first clamp head moves together with the first clamp handle at the moment, and the second clamp head moves together with the second clamp handle. From the above, the hemostatic forceps for thyroid surgery provided by the invention has the following beneficial effects. 1. Through the combined design of the built-in protruding part of the finger ring and the anti-skid groove, the stress area during operation is increased, the finger load is reduced, the holding slipping is avoided, the comfort and the operation reliability of long-time operation are improved, the embedding and separating operations of the lock catch are both matched with the natural actions of the fingers of an operator, the operation flow is smooth, and the redundant steps of the operation of the instrument can be reduced. 2. The locking mechanism can maintain continuous and stable clamping pressure, avoid the blood vessel from loosening in the clamping process, prevent tiny blood vessels from slipping off due to fine textures of the clamp head, disperse clamping stress, protect the fragile blood vessel wall of the thyroid region and reduce bleeding and tissue injury in operation.
