Description

Technical Field

[0001] This utility model relates to the field of medical forceps technology, specifically a tissue forceps. Background Technology

[0002] Tissue forceps, medical surgical tools, are generally used to clamp various human tissues, preventing slippage. The forceps beaks have teeth to improve clamping stability. For example, Chinese invention patent CN110507387A discloses a tissue clamping forceps, including handles, a pin, and forceps heads. The handles include a left handle and a right handle, each composed of a first handle and a second handle. The slope of the first handle is less than that of the second handle. The forceps heads include a left head and a right head, with interlocking strip-shaped meshing teeth and grooves on the lower inner wall of the left and right heads. However, current tissue forceps have the following drawbacks:

[0003] Tissue forceps hold tissues with their beaks, which have teeth to increase friction. The meshing of these teeth is very important. After prolonged use, the tissue forceps themselves are not easily worn down, but the teeth of the beaks are frequently engaged, which can cause them to wear down and become loose. This compromises the stability of tissue holding and renders the tissue forceps unusable, which is a huge waste.

[0004] Therefore, we propose a tissue forceps to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tissue forceps to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tissue forceps, comprising two forceps beaks, a main joint portion and a sub-joint portion, each forceps beak being provided with a biting component, a side opening being opened on one side of each forceps beak, the biting component being disposed on the side opening, the biting component including a clamping plate, the clamping plate being located inside the side opening, and multiple biting teeth being uniformly fixed to the side of the clamping plate away from the forceps beaks.

[0007] Preferably, the main joint has an opening on its inner side, with openings on both sides. The sub-joint is inserted into the opening, and a shaft is horizontally fixed to the middle of the opening. The shaft is rotatably sleeved onto the middle of the sub-joint. The top of the sub-joint is fixed to the bottom of one of the jaws, and the top of the main joint is fixed to the bottom of the other jaw.

[0008] Preferably, both the sub-joint and the main joint are provided with a clamp handle assembly at their bottom ends, and two finger rings are provided at the bottom ends of the two clamp handle assemblies, with one of the finger rings having a handle that is fixedly extended to its bottom.

[0010] Preferably, the pliers beak has multiple external holes on the side away from the side opening, and a threaded through hole is formed at the end of the external hole. The threaded through hole connects to the dovetail groove. The side wall of the dovetail bar has multiple threaded holes horizontally formed at the positions of the multiple external holes. The threaded through hole and the threaded hole are threadedly connected to a small bolt, and the head of the small bolt is located inside the external hole.

[0011] Preferably, the clamp handle assembly includes an upper stainless steel handle and a lower stainless steel handle, the bottom end of the upper stainless steel handle is fixed to the top end of the lower stainless steel handle, the connection between the upper and lower stainless steel handles is curved, a locking plate is fixed to the side wall of the lower stainless steel handle, a plurality of locking teeth are fixed to the side wall of the locking plate, and the top end of the upper stainless steel handle is fixed to the bottom end of the main joint or the sub-joint.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-2 This utility model provides a technical solution: a tissue forceps, including a jaw 1, a main joint 3 and a sub-joint 31. Each jaw 1 is provided with a biting component 2. A side opening 11 is opened on one side of the jaw 1. The biting component 2 is disposed on the side opening 11. The biting component 2 includes a clamping plate 21, which is located inside the side opening 11. Multiple biting teeth 25 are evenly fixed to the side of the clamping plate 21 away from the jaw 1. The biting component 2 with biting teeth 25 is separated from the jaw 1 and can be installed and replaced. On the one hand, different types of tooth shapes of biting components 2 can be replaced according to different tissues being clamped. On the other hand, when the biting teeth 25 are worn, the biting component 2 can be directly replaced without scrapping the entire forceps body, thus avoiding waste.

[0022] Example 2:

[0023] Please see Figure 1-4 This is the second embodiment of the present invention. Based on the previous embodiment, the main joint 3 has an opening 32 on the inner side. Both sides of the opening 32 are open structures. The sub-joint 31 is inserted into the opening 32. The middle of the opening 32 is horizontally fixed to the shaft 33. The shaft 33 is rotatably sleeved to the middle of the sub-joint 31. The top of the sub-joint 31 is fixed to the bottom of one of the jaws 1. The top of the main joint 3 is fixed to the bottom of the other jaw 1.

[0024] Both the sub-joint 31 and the main joint 3 are provided with a clamp handle assembly 4 at their bottom ends. The bottom ends of the two clamp handle assemblies 4 are provided with two finger rings 5, one of which is fixed to the bottom of the extended handle 51.

[0025] A dovetail groove 12 is opened on the side wall of the side opening 11. The top of the dovetail groove 12 is an open structure.
