Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a surgical dissector which is easy to install. Background Art

[0002] During intracranial tumor resection, doctors use a surgical dissector to separate the tumor from surrounding tissue. Surgical dissectors are also used in surgeries such as meningioma resection and acoustic neuroma resection.

[0003] When using existing surgical dissectors, medical personnel need to hold the dissector continuously to dissect tissues. When performing more complex surgeries, the operation time is generally longer. Continuously holding the dissector can easily cause soreness in the user's wrist, affecting the accuracy of tissue dissectability. Therefore, a surgical dissector that is easy to install is needed to solve the above problem. Utility Model Content

[0004] The purpose of the present utility model is to provide a surgical dissector that is easy to install, so as to solve the problem raised in the above-mentioned background technology that the existing surgical dissector requires medical personnel to continuously hold the dissector to dissect tissues, etc. When performing more complicated operations, the operation time is generally longer, and continuously holding the dissector can easily make the user's wrist sore, affecting the accuracy of tissue dissect.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a surgical dissector that is easy to install, comprising:

[0007] stripper;

[0008] The fixing mechanism includes a first frame and a second frame symmetrically and slidingly connected in the middle of the outer wall of the peeling sub-circle, the first frame is equal in size to the second frame, the outer walls of the first and second frames are fixedly connected with a connecting frame, the inner wall of the connecting frame is fixedly connected with connecting springs at equal intervals around the circumference, and the outer wall of the end of the connecting spring is fixedly connected with a clamping pad.

[0009] Furthermore, it also includes a first limiting mechanism, which includes first limiting holes equidistantly arranged on the outer wall of the peeling subcircle around the circumference, and a first spring is fixedly connected to the inner wall of the first limiting hole.

[0010] Furthermore, the end of the first spring is fixedly connected to a first limiting head, and the outer walls of the first bracket and the second bracket are provided with extension holes corresponding to the first limiting head.

[0011] Furthermore, it also includes a second limiting mechanism, which includes a second limiting hole opened in the inner cavity of the first sleeve and the second sleeve, and the inner wall of the second limiting hole of the first sleeve is fixedly connected to the connecting tube.

[0012] Furthermore, a corresponding hole is formed through the end of the inner wall of the connecting cylinder, and a second limiting head is symmetrically and slidably connected to the inner wall of the corresponding hole, and a second spring is fixedly connected between the two second limiting heads.

[0013] Furthermore, it also includes a disassembly mechanism, which includes a thread opened on the outer wall of the circumference of the end of the stripper, the threaded outer wall is threadedly connected to an engaging sleeve, and the outer wall of the end of the engaging sleeve is fixedly connected to a joint.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. According to the present invention, when the peeler is needed, the user inserts the index finger and the middle finger into the corresponding connecting frame. During the process of inserting the fingers into the connecting frame, the movement of the fingers pushes the clamping pad, and the clamping pad squeezes the connecting spring. When the index finger and the middle finger are in the appropriate position, the fingers stop moving, the pushing force on the clamping pad disappears, and the connecting spring rebounds to move the clamping pad to a position close to the fingers, clamping the fingers, so that the entire device is fixed on the fingers, which can avoid the user's need to continuously apply grip force to the peeler, ensuring that the user can accurately control the peeler in the second half of the procedure.

[0016] When the first and second brackets are rotated to the appropriate first limiting holes, they stop rotating, and the first spring rebounds to make the first limiting head extend out of the extension hole to limit the first and second brackets. The brackets can be completely disassembled and cleaned during cleaning. The fixing mechanism can be rotated, and the brackets can be used at various angles. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0027] See also Figure 1-4 As shown, this embodiment is a surgical dissector that is easy to install, comprising:

[0028] Stripper 1;

[0029] The peeling device 1 can be used to peel off the tissue surrounding the diseased body;

[0030] The fixing mechanism includes a first frame 201 and a second frame 202 symmetrically connected in a sliding manner in the middle of the outer wall of the stripper 1. The first frame 201 is equal in size to the second frame 202. The outer walls of the first frame 201 and the second frame 202 are fixedly connected to a connecting frame 203. The inner wall of the connecting frame 203 is fixedly connected to connecting springs 204 at equal intervals around the circumference. The outer wall of the end of the connecting spring 204 is fixedly connected to a clamping pad 205.

[0031] The first frame 201 and the second frame 202 are supported by the stripper 1, the connecting frame 203 is supported by the first frame 201 and the second frame 202, the connecting spring 204 is supported by the connecting frame 203, the clamping pad 205 is driven to move by the expansion and contraction of the connecting spring 204, and the finger is clamped by the clamping pad 205.

[0032] Working principle:

[0033] When the peeler 1 needs to be used, the user inserts the index finger and the middle finger into the corresponding connecting frame 203. During the process of inserting the fingers into the connecting frame 203, the movement of the fingers pushes the clamping pad 205, and the clamping pad 205 squeezes the connecting spring 204. When the index finger and the middle finger are in the appropriate position, the fingers stop moving, the pushing force on the clamping pad 205 disappears, and the connecting spring 204 rebounds to move the clamping pad 205 to a position close to the finger, clamping the finger, so that the entire device is fixed on the finger.

[0034] This step can avoid the user having to continuously apply grip force to the peeling tool 1, ensuring that the user can accurately control the peeling tool 1 in the second half of the procedure.

[0035] See also Figure 1-4 This embodiment is based on the above embodiment and further includes:

[0036] The first limiting mechanism includes first limiting holes 301 equidistantly arranged on the outer wall of the stripper 1 around the circumference, and a first spring 302 is fixedly connected to the inner wall of the first limiting hole 301;
