[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0022] like Figure 1 , Figure 4 As shown, this application provides a neurosurgical microsurgical tumor removal forceps, including: a head 1, a body 2, and a tail 3. The tail 3 is located at the rear end of the two body parts 2. The head 1 is located at the front end of the body part 2. The head 1 has a tumor removal spoon 11. The body part includes a main body 21, a connecting part 22, and a handle 23. The main body 21 is connected to the handle 23 via the curved connecting part 22. The outer side of the handle 23 has a protrusion 230. The inner side of the handle 23 away from the tail has a cylindrical protrusion 231 to prevent deformation of the tumor removal forceps. Figure 3 The cylindrical protrusion on the handle is 3-4mm in diameter and 1-2mm in height, which prevents excessive force on the tumor retrieval spoon and solves the problem of deformation of the tumor retrieval spoon after prolonged use. It can also prevent the surgeon from deforming or damaging the tumor retrieval forceps due to excessive force. The total weight of the tumor retrieval forceps is 45-47g, and the total length is 230-250mm. The tumor retrieval forceps model is named according to the maximum diameter of the head, and the sizes include 1mm, 2mm, 3mm, 4mm, etc. In this example, the head distance is 11-13mm.

[0023] Preferably, the head 1 is oval or other shape suitable for removing deep brain tumors.

[0024] Specifically, such as Figure 4 As shown, the tumor-removing spoon 11 has an elliptical, circular, and a combination of elliptical and semi-circular structures, with a length of 2-4 mm.

[0025] Preferably, the main body 21 has a structure that gradually extends from the main body to the connecting part. The length of the main body is 110-130mm, and the width gradually decreases from 4-5mm at the connecting part to 1-2mm at the tip of the tweezers. The distance between the left and right main body portions gradually increases from 9-11mm to 11-13mm at the tip of the tweezers.

[0026] Preferably, the tip of the main body matches the head 1. The elongated shape of the main body effectively prevents the instrument from obstructing the surgical area. A good field of vision helps protect structures surrounding the tumor, such as important nerves and blood vessels.

[0027] Preferred, such as Figure 2As shown, the connecting part 22 is disposed between the connecting main body and the handheld part, including a first angled structure 221 and a second angled structure 222. The first angled structure is connected to the main body 21, and the second angled structure is connected to the handheld part 23. Both the first and second angled structures are 120-degree obtuse angles. The connecting part is 4-6mm wide and 14-16mm long, and is formed by two 120-degree obtuse angle arcs connecting the main body of the forceps to the handheld part. The large arc angle can effectively avoid the surgeon's fingers from obstructing the surgical field. When the tumor forceps are held, they are tilted forward and downward, which can effectively solve the problem of narrow surgical field in microsurgical neurosurgery, keeping the surgeon's fingers outside the surgical field and preventing obstruction of the surgical area.

[0028] Preferably, the protrusion 230 is composed of multiple small protrusions. The inner surface of the handle is smooth, and the outer surface has a rounded protrusion. The length of the protrusion of the handle is 40-60mm. The width of the handle is 8-10mm, and the length is 40-50mm, which fully meets the requirements of different surgeons to hold the tumor removal forceps with their thumb, index finger, and middle finger.

[0029] Preferably, the small protrusions are composed of uneven rhombuses, rectangles, spheres, or rings. The protrusions are cut into multiple uneven, fine rhombus-shaped protrusions. This design enhances the tactile feel of the fingers, increases friction, and allows the operator to hold the device for extended periods without excessive finger fatigue.

[0030] Preferably, the tail, body, and end are all made of medical-grade stainless steel. The tail of the forceps is 50mm long, and the width of the handle gradually transitions smoothly from 8-10mm to 6-8mm at the tail end, with the tail tip measuring 19-21mm. The forceps are connected as a single unit to form the left and right parts. The total length of the tail and handle is 90-100mm, which is sufficient to allow different surgeons to hold the forceps with the tail positioned between their thumb and forefinger.

[0031] This utility model features a smooth and delicate overall design, effectively avoiding obstruction of the surgical field. 1. The overall design of this tumor retrieval forceps is spear-shaped, suitable for treating lesions in the sellar region and the posterior part of the third ventricle, solving the problem of deep and confined spaces in these areas and reducing the difficulty of surgery.
