Description

Laparoscopic needle holder with thread hanging function

technical field

The utility model belongs to the technical field of medical treatment, and in particular relates to a needle holder for an endoscope with the function of hanging a thread.

Background technique

When knotting the endoscopic needle holder, it is necessary to wrap the silk thread around the needle holder twice, then clamp the end of the thread, pull the end of the thread out of the wound coil, and tighten the thread to complete the knot, but winding with silk thread After the needle holder, the coil is easy to slip off from the head of the needle holder. At this time, it needs to be wound again. This knotting method is inconvenient to wind the silk thread, which is troublesome to operate and prolongs the operation time.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a needle holder for an endoscope with the function of hanging the thread, which can hang the thread, prevent the entangled thread from falling off, and facilitate knotting.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the endoscopic needle holder with the function of hanging the wire, including the head of the forceps, the body of the forceps, the handle seat and the handle of the forceps, and the body of the forceps is provided with a thread-hanging mechanism. The wire mechanism includes a handle, a push rod and two sets of wire hanging components. There is a chute on the handle seat, the handle is slidably connected in the chute, the push rod is installed in the pliers rod along the axial direction, and a support is fixed in the pliers rod. The support ring is set on the push rod, the front end of the push rod is fixed with a triangular block, the inner end of the handle extends into the clamp handle seat, the rear end of the push rod is connected with the inner end of the handle; the front rod of the clamp rod body There are two installation holes on the wall, and the two installation holes are symmetrical about the axis of the pliers rod body. Two sets of hanging wire components are respectively arranged in the two mounting holes. Each set of hanging wire components includes a hanging wire column, a spring and a connecting seat. The line post is installed in the installation hole, the radius of the line post is equal to the radius of the installation hole, the inner end of the line post is fixed with a wedge-shaped block, the connecting seat is fixed on the inner wall of the clamp rod and is located on the periphery of the installation hole, and the spring is set on the hanging On the line post, the two ends of the spring are respectively connected to the connecting seat and the wedge block;

The wedge-shaped blocks of the two groups of hanging wire components are fitted with the triangular blocks respectively.

By adopting the above technical scheme, the utility model has the following beneficial effects: when the utility model needs to be knotted with silk threads, by pushing the handle, the push rod is used to push the triangular block forward, and the triangular block starts to push forward, and the two groups of hanging wires The wedge-shaped block of the component fits the triangular block, and the shape of the wedge-shaped block and the triangular block, so the forward movement of the triangular block will push the two sets of hanging wire posts to move outward along the mounting holes. During the outward movement of the hanging wire posts, the spring Gradually compress, and finally the thread-hanging post is pushed out, and then the thread-hanging post can be used to hang the thread, preventing the silk thread wrapped around the head of the needle holder from falling off, which is convenient for knotting operation; after the knot is finished, two sets of thread-hanging posts are required Return to the mounting hole, pull the handle backward, and the handle pulls the triangular block backward through the push rod. Under the elastic force of the spring, the thread hanging post retracts into the mounting hole, which does not affect the normal use of the needle holder.

In summary, the utility model has a simple structure. Two sets of thread-hanging columns are added to the front of the pincer rod body of the needle holder. The two sets of thread-hanging columns are convenient for hanging the silk thread and prevent the thread from falling off when knotted. necessary trouble.

Detailed ways

As shown in Figure 1-3, the endoscopic needle holder with thread hanging function of the present utility model includes a forceps head 1, a forceps rod body 2, a forceps handle seat 3 and a forceps handle 4, and the forceps rod body 2 is provided with a hanging wire Mechanism, the wire hanging mechanism includes a handle 5, a push rod 6 and two sets of wire hanging components, a chute 20 is opened on the clamp handle seat 3, the handle 5 is slidably connected in the chute 20, and the push rod 6 is installed in the axial direction Inside the clamp rod body 2, a support ring 7 is fixed inside the clamp rod body 2, and the support ring 7 is sleeved on the push rod 6. The support ring 7 is used to support the push rod 6, and the front end of the push rod 6 is fixed with a triangular block 8. The inner end extends into the pincer handle seat 3, and the rear end of the push rod 6 is connected to the inner end of the handle 5; Axial symmetry, two sets of hanging wire components are respectively arranged in two mounting holes, each set of hanging wire components includes a hanging wire post 9, a spring 10 and a connecting seat 11, the hanging wire post 9 is installed in the installation hole, and the hanging wire post 9 The radius is equal to the radius of the mounting hole, the inner end of the wire hanging post 9 is fixed with a wedge-shaped block 12, the connecting seat 11 is fixed on the inner wall of the clamp rod body 2 and is located at the periphery of the mounting hole, the spring 10 is sleeved on the hanging wire post 9, and the spring 10 The two ends are respectively connected to the connecting seat 11 and the wedge block 12;

The wedge-shaped blocks 12 of the two groups of hanging wire assemblies are attached to the triangular blocks 8 respectively.

When the utility model needs to be used for silk knotting, by pushing the handle 5, the push rod 6 is used to push the triangular block 8 forward, and the triangular block 8 starts to push forward. Fit together, and the shape of the wedge block 12 and the triangular block 8, so the forward movement of the triangular block 8 will push the two sets of hanging posts 9 to move outward along the installation holes, and during the outward movement of the hanging posts 9, the spring 10 gradually Compression, the thread hanging post 9 is finally pushed out, and then the thread hanging post 9 can be used to hang the thread to prevent the silk thread wrapped around the head of the needle holder from falling off, which is convenient for knotting operation; after the knotting is completed, two sets of hanging thread are required The column 9 is retracted into the installation hole, and the handle 5 is pulled backward at this time, and the handle 5 pulls the triangular block 8 backward through the push rod 6. Under the elastic force of the spring 10, the hanging column 9 retracts into the installation hole without affecting Normal use of the needle holder.

This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model belong to the technology of the utility model. protection scope of the program.
