Description

Technical Field

[0001] The utility model relates to the field of tweezers, in particular to a pair of tweezers for orthopedic surgery. Background Art

[0002] During orthopedic surgery, doctors need tweezers for cleaning and disinfection. Existing tweezers have a simple structure, and it is difficult for doctors to control the force when clamping tiny objects. When the force is too strong, it may hurt or injure the patient. When the force is too weak, the clamped object may fall, requiring a second clamp, and the clamping effect is poor.

[0003] Chinese patent application No.: 201220039361.3 discloses a pair of suture-removing tweezers for surgery, comprising tweezers and a blade, wherein a blade is arranged on the lower edge of one side of the tweezers. The tweezers have a simple structure and it is difficult to control the force when clamping. When the force is too great, the patient may be hurt or injured. When the force is too small, the clamped object may fall and require secondary clamping, resulting in poor clamping effect. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model provides a pair of orthopedic surgical tweezers, which solves the technical problem of poor clamping effect of tweezers.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pair of orthopedic surgical tweezers comprises two clamping parts, wherein the clamping parts comprise a fixed plate, a buffer sheet, a hand-held plate, and a clamping end portion which are sequentially connected, the fixed plates of the two clamping parts are fixedly connected, the buffer sheet is a sheet-like structure, the thickness of the buffer sheet is less than the thickness of the fixed plate and the thickness of the hand-held plate, the buffer sheet can be bent and deformed, a hand-held part is provided on the hand-held plate, an anti-slip groove is provided on the hand-held part, a first limiting part is provided at the rear end of the inner side of the hand-held plate of at least one of the clamping parts, and a second limiting part is provided at the front end of the hand-held plate of at least one of the clamping parts.

[0007] Further:

[0008] The first limiting portion and the second limiting portion include at least one convex point, and the convex point can abut against another clamping portion.

[0009] The outer side surface of the fixing plate is flush with the outer side surface of the buffer sheet, and the inner side surface of the buffer sheet is flush with the inner side surface of the hand-held plate.

[0010] The hand-held portion is provided with a waist-shaped hole, which extends from the front end to the rear end of the hand-held portion, and the anti-slip grooves are arranged on both sides of the waist-shaped hole.

[0011] The anti-slip groove is in a wave shape.

[0012] A clamping plane is provided on the inner wall of the lower end of the clamping end portion.

[0013] The area of ​​the clamping end portion gradually decreases along the lower end direction.

[0014] The two fixing plates are connected to form a fixing portion, and the length of the fixing portion is 1 cm to 5 cm.

[0015] The two fixing plates are integrally formed through the fixing portion.

[0016] The length of the fixing portion is 3 cm.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] When the clamping part of the utility model clamps, when clamping to a certain angle, the first limiting part abuts against the rear end of the hand-held plate, giving the hand a reverse force. The hand needs a greater force to continue pressing the clamping part. During the pressing process, the buffer sheet can be deformed for buffering to prevent the fixing part from being damaged. The buffer sheet gives the hand a certain reverse force. The smaller the clamping angle, the greater the force applied to the hand, until the clamping end clamps the object. If the force is too large, the second limiting part abuts against the hand-held part to prevent the object from being broken by the excessive force and causing it to fall. This structure can better control the force of the tweezers, prevent pain or injury to the patient, and improve the effect of clamping the object. Furthermore, the first limiting part and the second limiting part are convex point structures with a simple structure. Furthermore, the outer side surface of the fixing plate and the outer side surface of the buffer sheet are The surface is flush, and the inner side surface of the buffer sheet is flush with the inner side surface of the hand-held plate, which is conducive to the deformation of the buffer sheet during the clamping process; further, the setting of the waist-shaped hole can improve the anti-slip effect. When clamped to a certain angle, parts of two fingers can pass through the waist-shaped hole and touch each other, and the fingers have a sense of touch, which has a good clamping effect; further, the anti-slip groove is wavy in shape, which is comfortable for fingers to press, and it is not easy for fingers to leave marks, and the anti-slip effect is better; further, the two clamping planes are clamped, which can be more stable; further, the area of ​​the clamping end portion gradually decreases along the lower end direction, which can penetrate deep into the human body and is not easy to touch the human body, thereby increasing the stability of clamping; further, the length of the fixing portion is longer, and when the buffer sheet is deformed and exerts force on the fixing portion, the fixing portion is not easy to wear or crack.
