Description

Technical Field

[0001] This utility model relates to a spinal tumor dissector that is easy to assemble. Background Technology

[0002] Currently, the procedure of removing spinal tumors is frequently encountered in surgical operations. The usual practice is to make a small incision in the outer capsule of the tumor and then insert a tumor dissector to separate it.

[0003] Most existing tumor dissection devices are one-piece structures, disposable consumables that are discarded after use, resulting in high operating costs. Some modular tumor dissection devices have complex assembly and disassembly mechanisms, making them inconvenient to use. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a spinal tumor dissector that is easy to assemble. It has a simple, reasonable and reliable structure, and allows for quick assembly and disassembly of the handle and disassembly rod, thereby improving ease of assembly and disassembly and reducing maintenance costs.

[0005] To solve the above-mentioned technical problems, the present invention provides a conveniently assembled spinal tumor dissector, comprising a handle, a dissector rod, and a positioning component. The front end of the handle has a recessed insertion hole, the rear end of the dissector rod is inserted into the insertion hole for positioning, the front end of the dissector rod has a hook-shaped structure, and the handle and the dissector rod have corresponding positioning holes longitudinally penetrating through the insertion hole. The positioning component is disposed on the outside of the handle and passes through the positioning hole to fix the handle and the dissector rod accordingly.

[0006] In a preferred embodiment of the present invention, a protruding positioning block is provided at the bottom of the insertion hole.

[0007] In a preferred embodiment of the present invention, the bottom of the rear end of the peeling rod is provided with a recessed positioning groove corresponding to the positioning block.

[0008] In a preferred embodiment of the present invention, the positioning element includes an elastic cord and a rivet.

[0009] In a preferred embodiment of the present invention, the elastic loop is fitted over the outside of the handle, and the top of the rivet is provided with an mounting hole and connected to the elastic loop.

[0010] In a preferred embodiment of the present invention, the handle is provided with a limiting groove recessed in the elastic loop.

[0011] In a preferred embodiment of this utility model, the handle is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are: the spinal tumor dissector disclosed in this utility model is easy to assemble, has a simple, reasonable and reliable structure, and can facilitate the quick loading and unloading of the handle and the dissector rod, thereby improving the ease of loading and unloading and reducing maintenance costs. Attached Figure Description

[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort, wherein: Figure 1 This is a partial cross-sectional view of a preferred embodiment of a spinal tumor dissector that is easy to assemble according to the present invention; Figure 2 yes Figure 1 A magnified view of part A. Detailed Implementation

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figures 1-2 As shown, the embodiments of this utility model include: A spinal tumor dissector that is easy to assemble includes a handle 1, a dissector 2, and a positioning element.

[0016] The handle 1 is provided with anti-slip texture 3 to facilitate the grip of medical personnel and prevent slippage.

[0017] The front end of the handle 1 has a recessed insertion hole 4, and the rear end of the peeling rod 2 is inserted into the insertion hole 4 for positioning, so as to realize the detachable assembly of the handle 1 and the peeling rod 2.

[0018] The front end of the peeling rod 2 has a hook-like structure to facilitate the removal of tumors.

[0019] The bottom of the insertion hole 4 is provided with a protruding positioning block 5, and the bottom of the rear end of the peeling rod 2 is provided with a concave positioning groove 6 corresponding to the positioning block 5, so that the peeling rod 2 can be accurately positioned with the handle 1 when inserted.

[0020] The handle 1 and the peeling rod 2 are longitudinally provided with corresponding positioning holes 7 in the middle of the insertion hole 4. The positioning element is provided on the outside of the handle 1 and passes through the positioning hole 7 to fix the handle 1 and the peeling rod 2 accordingly, so as to achieve stable fixation of the handle 1 and the peeling rod 2.

[0021] The positioning component includes an elastic cord 8 and a rivet 9.

[0022] The elastic loop 8 is fitted over the handle 1. The rivet 9 has a mounting hole 10 at its top and is connected to the elastic loop 8. Normally, the elastic loop 8 is fitted over the handle 1, and the rivet 9 is inserted into the positioning hole 7, preventing it from being lost. When the peeling rod 2 needs to be assembled, simply lift the top of the rivet 9, insert the peeling rod 2 to the bottom of the insertion hole 4, aligning the positioning hole 7. Loosen the rivet 9, and the elastic loop 8 will allow it to be inserted into the positioning hole 7 for fixation.

[0023] The handle 1 has a recessed limiting groove 11 at the elastic loop 8, which facilitates the quick positioning of the elastic loop 8 and avoids the elastic loop 8 being exposed to the outside of the handle 1, thus preventing unnecessary impact.

[0024] In summary, the spinal tumor dissector disclosed in this utility model is easy to assemble, has a simple, reasonable, and reliable structure, and allows for quick assembly and disassembly of the handle and disassembly rod, improving ease of assembly and disassembly and reducing maintenance costs.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
