Description

Surgical knife

Technical Field

The utility model relates to a special surgical instruments field especially relates to a scalpel.

Background

In the existing ureter cutting operation, the skin is generally cut off by scissors or the electric knife is used for cutting, but the two cutting operations are harmful to the human body, the scissors are not easy to operate, when the electric knife is used, the electric knife needs to be clamped by a clamp, when the electric knife is arranged on the clamp, the hand is easy to scratch, and after the electric knife is used for multiple times, the electric knife can become dull, the use cost is high, and the electric knife is not easy to use; in addition, in the ureter cutting operation, a repetitive cutter is used, but this cutter needs to be sterilized after each use, and the blade of the cutter becomes dull with the increase of the number of times of sterilization, which increases the cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a scalpel, it can overcome above-mentioned inconvenient, the with high costs defect of operation.

To achieve the above object, the solution of the present invention is:

a scalpel for ureteral surgery comprising a single-use blade and a connecting rod, the blade being connected to the connecting rod.

Further, the connecting rod is connected with the blade through a breakable connecting part.

Further, the blade includes a sharp end and a blunt end, the blunt end being connected to the connecting rod through the connecting portion.

Further, the blade has a curvature.

Further, the sharp end is arranged at the upper end of the blade.

Further, the area of the sharp end occupies at least one third of the area of the blade

Further, the cutting device further comprises a clamping device for clamping the blade.

After the technical scheme is adopted, the scalpel has a simple and convenient structure, the blade is used for one time, multiple disinfection is not needed, the blade is prevented from being dulled due to multiple disinfection, the usage is convenient and rapid, and the operation is simple; for the scalpel that adopts electrotome and metal or ceramic to make, material saving is with low costs, and can not cause the harm to the human body, when getting the put blade, can avoid blade fish tail hand through the connecting rod of taking, strengthens the security of using.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example (b):

as shown in fig. 1, a surgical knife for ureteral surgery, which is mainly used in match with a laparoscope, comprises a disposable blade 1 and a connecting rod 2, wherein the blade 1 is connected with the connecting rod 2.

By adopting the structure, the disposable scalpel blade 1 reduces the abrasion degree of the blade 1, so that the ureter can be efficiently and accurately incised, the operation can be smoothly performed, the disposable scalpel which can be conveniently taken is designed by the connecting rod 2, and the hand injury caused by the medical care personnel when the blade 1 is taken and placed is prevented.

As shown in fig. 2, further, the connecting rod 2 is connected to the blade 1 by a breakable connection 3.

With this structure, the connecting rod 2 is connected to the blade 1 through the breakable connecting portion 3, that is, in use, the application environment of the blade 1 can be increased by breaking the blade 1 and the connecting rod 2 apart.

Referring to fig. 1, further, the blade 1 includes a sharp end 11 and a blunt end 12, and the blunt end 12 is connected to the connecting rod 2 through the connecting portion 3.

As shown in figure 1, the blunt end 12 of the blade 1 is connected with the connecting rod 2 through the connecting part 3, so that the sharpness of the blade 1 is prevented from being influenced, the blade 1 is convenient to take and does not hurt hands.

Further, the sharp end 11 is provided at the upper end of the blade 1.

As shown in fig. 1, and the area of the sharp end 11 occupies at least one third of the area of the blade 1; the use of a portion of the sharp end 11 avoids inadvertent injury to vascular tissue in the remainder of the blade 1.

Only the upper end of the blade 1 is provided with a sharp end 11, and the part of the sharp end is a blunt end 12, so that the damage of the rest part to the ureter of a patient during operation is avoided, and the operability of the disposable scalpel is enhanced; the blade 1 is small, typically 6-12mm in length, in particular 8mm in this embodiment, and the blade 1 comprises a sharp end 11 and a blunt end 12, the sharp end 11 being located in the upper region of the blade 1, in particular only the sharp end 11 being 3mm in the upper end of the blade 1.

As shown in fig. 3, the scalpel further comprises a clamping device 4 for clamping the blade 1. In this embodiment, the disposable blade 1 is mainly clamped by a small clamp in ureteral surgery, so that the convenience of operation is increased.

When the scalpel is used, the blunt end 12 of the scalpel blade 1 is fixed on the clamping device 4 through the connecting rod 2, then the connecting part 3 which can be broken off is broken, namely the connecting rod 2 and the scalpel blade 1 are separated, then the disposable scalpel blade 1 and the clamping device 4 are combined to form the scalpel, after the scalpel is used, only the scalpel blade 1 needs to be replaced and discarded, the clamping device 4 can be used subsequently, the increase of cost is reduced, and meanwhile, the operation convenience of an operation is also improved.

Specifically, the beneficial effects are as follows:

1. the connecting rod 2 which can be broken is used, so that medical staff can conveniently take the blade 1 without scratching hands, and after the blade is clamped by the clamping device 4, the connecting rod 2 is broken for operation, so that the use is convenient;

2. the disposable blade 1 is used, so that the blade 1 can be prevented from being passivated due to repeated disinfection, and the safety and rapidity of the operation are prevented from being influenced;

3. only a part of the sharp end 11 is used, so that other vascular tissues can be prevented from being accidentally injured by the rest parts of the blade 1 in the operation process;

the above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
