Description

Technical Field

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

[0002] A tissue dissector, also known as a small needle knife, is a surgical instrument used for dissecting tissue. Most existing medical dissectors consist of a plastic handle with a stainless steel needle knife, and only the tip is sharpened. Because of the gap and obstruction between the handle and the needle body, these dissectors often obstruct the view when held by hand. Furthermore, the only-sharpened tip requires repeated adjustments to the needle knife position during tissue dissection, resulting in low dissection efficiency and cumbersome operation. Therefore, we propose a new medical tissue dissector. Summary of the Invention

[0003] The purpose of this invention is to provide a medical dissector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a medical dissector, comprising a needle rod, a handle connected to the bottom end of the needle rod, a connecting mouth provided at the connection between the handle and the needle rod, a blade provided at the top end of the needle rod, a front blade provided at the top end of the blade, and side blades provided on the left and right sides of the blade, and scale lines provided on the sides of the blade and the needle rod.

[0005] Preferably, the needle bar is 5cm long, cylindrical in shape, and has an outer diameter of 1.1mm.

[0006] Preferably, the blade is 5mm long, flat, and the widest part of the blade is about 1.2mm.

[0007] Preferably, the width of the front cutting edge is 1.1 mm, and the end is parallel to the scale line, with the end of the front cutting edge being the zero mark of the scale line.

[0008] Preferably, the junction between the side blade and the blade head has a smooth arc surface.

[0009] Preferably, the handle is generally teardrop-shaped, and the connection between the nozzle and the needle bar is streamlined.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This medical dissector, with its multi-faceted blade head having side and front blades, can perform tissue dissection operations from both the front and side, improving the efficiency of the dissection operation and making it more convenient and practical to use; the integrated teardrop-shaped handle, connecting nozzle, and needle bar make the grip operation more convenient and comfortable, and also reduce the obstruction of the grip's field of vision; combined with the set scale lines, it can perform dissection operations quickly and accurately.

[0014] 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.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a medical dissector, including a needle rod 1, which is 5cm long, cylindrical in shape, and has an outer diameter of 1.1mm. The surface of the needle rod 1 is smooth. A handle 2 is connected to the bottom of the needle rod 1. A connecting nozzle 21 is provided at the connection between the handle 2 and the needle rod 1. The handle 2 is teardrop-shaped, and the connection between the connecting nozzle 21 and the needle rod 1 is streamlined. The needle rod 1, handle 2, and connecting nozzle 21 are integrally formed without gaps. The streamlined connection, which is easily accessible to the hand, makes it more comfortable and convenient to hold. The transition lines at the connection are obvious, making it easier to observe. A blade 3 is provided at the top of the needle rod 1. The blade 3 is 5mm long, flat, and approximately 1.2mm wide at its widest point. The blade 3 is slightly wider than the needle rod 1, which improves the surgical dissection operation. The observation and operation are more convenient and practical. The top of the blade head 3 has a front blade 31, and the left and right sides of the blade head 3 have side blades 32. The blade head 3 and the needle bar 1 have scale lines 4 on their sides. The side blades 32 are located on the sides, and the front blades 31 are located at the ends. Both the front end and the side of the blade head 3 can be used for tissue dissection, which can improve the efficiency of the dissection operation and make it more convenient and practical to use. The width of the front blade 31 is 1.1mm, and the end is parallel to the scale line 4. The end of the front blade 31 is the zero mark of the scale line 4, which can accurately observe the length of the dissector penetrating the tissue. This makes it convenient to operate according to the penetration length in the case of poor visibility and meets the operational needs of special situations. The connection between the side blades 32 and the blade head 3 is a smooth arc surface, which ensures the overall flatness of the blade head 3 and ensures that the entire front and rear surfaces of the blade head 3 are smooth.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
