Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to an ultrasonic scalpel for cutting and hemostasis. Background Art

[0002] An ultrasonic scalpel is a high-frequency electrosurgical device, which is mainly used for cutting biological tissues and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and quick recovery after surgery. It acts on human tissues to cut and coagulate without causing side effects such as tissue drying and burns. No electric current passes through the human body when the blade is working. It is widely used in operating rooms and is known as a bloodless scalpel.

[0003] A Chinese patent with publication number CN218045274U discloses an ultrasonic surgical knife for cutting and hemostasis, comprising an ultrasonic handle, a rotating part arranged at one end of the ultrasonic handle, an ultrasonic guide rod, an ultrasonic blade head arranged at one end of the ultrasonic guide rod, and a pressure sensor arranged on the ultrasonic blade head, wherein the ultrasonic guide rod comprises an outer sleeve rod, a driving rod installed inside the outer sleeve rod, and a conduction rod; the ultrasonic blade head comprises a blade body, a clamping part arranged on the blade body, a mounting part, and a mounting screw connecting the mounting part and the clamping part; the mounting screw comprises a connecting rod, a knob end arranged at the end of the connecting rod, a limiting part fixed to the knob end, and a spring sleeved on the connecting rod. The ultrasonic surgical knife for cutting and hemostasis of the utility model is fixed by a mounting screw, thereby improving the stability of the ultrasonic blade head. The above technical solution increases the stability of the blade through the pressure of the spring. However, in actual use, due to a small amount of bleeding, the working temperature of the ultrasonic knife is only about 60 to 70 degrees, which is a low-temperature operation. However, this temperature will also accelerate the coagulation of blood, and after coagulation, a large amount of blood will be adsorbed on the blade. These adherent tissues may enter the amplitude rod along the working end of the blade, reducing the vibration efficiency, resulting in slow cutting speed and poor hemostasis effect, affecting the progress of the operation.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an ultrasonic surgical knife for cutting and hemostasis.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0026] The utility model will now be further described in detail with reference to the accompanying drawings.

[0027] See also Figure 1-4 As shown, in this embodiment, an ultrasonic surgical knife for cutting and hemostasis is provided, comprising a handle 1, an output end of the handle 1 is fixedly connected to a knife holder 2, a knife head 3 is mounted on one side of the knife holder 2, and a clamping plate 4 is rotatably matched on the upper side of the knife head 3;

[0028] The lower side of the handle 1 is rotatably matched with a trigger 5 that matches with the splint 4, and a movable opening 6 is opened on one side of the trigger 5. A blood draw tube 7 is fixedly connected to one side of the handle 1, and a piston 8 is slidably matched inside the blood draw tube 7. A sliding rod 9 located inside the movable opening 6 is fixedly connected to one side of the piston 8, and a push-back plate 10 is fixedly connected to one side of the sliding rod 9. A hose 11 that matches with the cutter head 3 is installed on the upper side of the piston 8.

[0029] One aspect of the application of this embodiment is that when in use, the handle 1 can be held and the trigger 5 can be pulled to rotate, which can drive the splint 4 to tighten and contact the blade head 3 to achieve the effect of suturing and stopping bleeding of the surgical blood vessels;

[0030] However, at the extraction position, although the ultrasonic scalpel can reduce bleeding, a small amount of blood will still appear. When there is a small amount of blood accumulated at the treatment position, one end of the hose 11 can be inserted into the blood accumulated part. When the trigger 5 is pulled, the push back plate 10 will be pulled to one side, and the piston 8 will be pulled by the sliding rod 9 to generate pressure in the blood extraction tube 7, thereby increasing the suction force in the hose 11 to extract the accumulated blood, thereby avoiding the situation where the accumulated blood affects the operation or the blood coagulation adsorbs the blade 3 and affects the progress of the operation.

[0031] By setting the sliding rod 9, it can be achieved that during operation, if there is blood accumulation at the operating position, the sliding rod 9 can be pulled to move the piston 8 in the blood draw tube 7, so that suction is generated in the blood draw tube 7, and the accumulated blood is sucked out through the hose 11, thereby avoiding the situation where the accumulated blood affects the operation or the blood coagulation and adsorption of the blade 3 affects the progress of the operation, thereby improving the convenience of use during the operation.

[0032] A pressure sensor 12 is installed on the upper side of the tool holder 2 of this embodiment. The pressure sensor 12 is used to measure the clamping pressure of the object clamped by the tool holder 2 to avoid the possibility of organ injury caused by excessive clamping.

[0033] The handle 1 of this embodiment is equipped with an anti-skid cover 13, and a plurality of anti-skid grooves 14 are formed on the anti-skid cover 13. The anti-skid cover 13 and the anti-skid grooves 14 are convenient for increasing the friction of the handle 1 when a person holds the handle 1, thereby reducing the sliding of the handle 1 due to low friction during use, thereby affecting the use effect.

[0034] In this embodiment, the lower sides of the tool holder 2 and the tool head 3 are both provided with a clamping ring 15 that matches the hose 11 , and the clamping ring 15 is convenient for fixing the hose 11 .
