[0029] See Figures 1 to 2 Shown is an ultrasonic scalpel to which the handle protective cover of an embodiment of the present invention is applicable. The ultrasonic scalpel includes a handle 10, a tool 20, and a power cord 30. The rear end of the tool 20 is connected to the front part of the handle 10, and the power cord 30 is connected to the lower part of the handle 10. Among them, the tool 20 includes a main body part 201 and a connection head 202 located at the rear of the main body part 201. When the tool 20 is connected to the handle 10, the connection head 202 is inserted into the inside of the handle 10 and connected to the connection mechanism inside the handle 10. A knob 101 is provided at the front part of the handle 10. When the knob 101 is rotated, the tool 20 can be driven to rotate, so as to switch the cutting angle and position of the tool 20, etc.

[0030] See Figure 3 、 Figure 4 Shown is a handle protective cover for an ultrasonic scalpel, which can cooperate with the above ultrasonic scalpel to mainly protect the handle 10 from being contaminated when the ultrasonic scalpel performs surgical operations.

[0031] See Figure 1 As shown, the handle protective cover includes a sleeve body 1. The sleeve body 1 includes a main body part 11 and a first extension part 12 with interconnected inner cavities. The first extension part 12 extends forward from the front end of the main body part 11. A main entrance 14 is provided at the upper part of the main body part 11, and a first opening 15 is provided at the front end of the first extension part 12. Among them, the main body part 11 is configured to allow the handle 10 to be placed through the main entrance 14, and the first extension part 12 is configured to allow the tool 20 to penetrate along the length direction through the first opening 15. When setting, the outer contour of the main body part 11 is similar to the outer contour of the handle 10, and the inner cavity of the main body part 11 is larger than the volume of the handle 10; the aperture of the first extension part 12 is larger than the maximum diameter on the tool 20, so that the tool 20 can penetrate into the first extension part 12 along its own length direction and be connected to the handle 10.

[0032] The handle protective cover further includes a main sealing member 3 and a first sealing member 4. Among them, the main sealing member 3 is provided on the upper part of the main body part 11 and is used to close the main entrance 14, and the first sealing member 4 is provided on the first extension part 12 and is used to fix the first extension part 12 on the tool 20. Among them:

[0033] The main sealing member 3 is disposed on the side wall of the main inlet 14 extending in the front-rear direction. The main sealing member 3 includes a wire that can be bent and deformed along its own length direction, and a plastic strip coated on the outer peripheral portion of the wire, and is adhesively fixed to the side wall of the main inlet 14 by the plastic strip. In the same main sealing member 3, the number of wires can be one or multiple wires arranged in parallel; the main sealing member 3 can be set as one or multiple ones arranged at intervals in the up-down direction. After the main sealing member 3 is bent along the length direction, the main sealing member 3 can close the two side portions of the main inlet 14 relative to each other and keep them in a closed state, thereby closing the main inlet 14. In other embodiments, the main sealing member 3 can also adopt a self-sealing strip or other structures capable of closing the main inlet 14.

[0034] The structure of the first sealing member 4 is similar to that of the main sealing member 3. It also includes a wire that can be bent and deformed along its own length direction, and a plastic strip coated on the outer peripheral portion of the wire, and is adhesively fixed to the outside of the first extension portion 12 by the plastic strip. The first sealing member 4 extends in the up-down direction, and at least a part of the first sealing member 4 overhangs outside the first extension portion 12. After the first sealing member 4 is wound and bent and deformed, the first extension portion 12 can be wrapped around the outer peripheral wall of the tool 20, so that the first opening 15 is closed. The first sealing member 4 can be set as multiple ones arranged at intervals in the front-rear direction to increase the sealing effect at the first opening 15 and avoid the risk of blood, tissue fluid, etc. entering due to the gap between the outer peripheral portion of the tool 20 and the first extension portion 12.

[0035] In this embodiment, the sleeve body 1 further includes a second extension portion 13 whose inner cavity communicates with the main body portion 11. The second extension portion 13 extends downward from the lower end of the main body portion 11. A second opening 16 is provided at the lower portion of the second extension portion 13. The second extension portion 13 can allow the power cord 30 to pass through from the second opening 16. A drawstring 5 is also provided at the second opening 16. The drawstring 5 can adopt a cord. Since the second extension portion 13 is mainly used to accommodate the power cord 30 and its length is usually long, and the position of the drawstring 5 is usually far from the surgical site with a small pollution risk, only a slight binding and fixing is required at the drawstring 5.

[0036] When the handle protective cover is used in cooperation with the ultrasonic scalpel, first separate the handle 10, the cutting tool 20 and the power cord 30 in the ultrasonic scalpel. Then, first place the handle 10 into the inner cavity of the main body 11 through the main entrance 14, wind the upper part of the main body 11 several times continuously, and wind the main sealing member 3 around it, so that the two side walls of the main entrance 14 are relatively closed. Subsequently, bend the two ends of the main sealing member 3 along the length direction, so that the main entrance 14 remains in a closed state, which can further increase the sealing effect of the main entrance 14 and prevent external dirt from entering the sleeve body 1. Subsequently, insert the connecting head 202 of the cutting tool 20 through the first opening 15 into the first extension part 12, and cooperate and connect it with the handle 10. Then, rotate the first sealing member 4 along the circumferential direction of the cutting tool 20, so that the first sealing member 4 presses the first extension part 12 against the outer circumferential wall of the cutting tool 20, closing the first opening 15. Finally, insert the power cord 30 into the second extension part 13 through the second opening 16, connect it to the lower part of the handle 10, and then close the second opening 16 with the drawstring 5. In this way, except for the main body part 201 of the cutting tool 20 that needs to be exposed for surgical operations, other parts of the ultrasonic scalpel are covered in the handle protective cover for full protection, preventing blood or tissue fluid from contaminating the handle 10 and the power cord 30 during the operation, reducing the pollution risk and the workload of cleaning and disinfection.

[0037] See Figure 3 , Figure 4 As shown in the figure, the handle protective cover further includes a finger set 2. The finger set 2 has a group provided on the left or right side of the sleeve body 1, or the finger set 2 is provided on both the left and right sides of the sleeve body 1 to facilitate the corresponding cooperation of both the left and right hands of the operator for operation. A finger sleeve channel for the finger to penetrate is formed between the finger set 2 and the sleeve body 1. Among them, the finger set 2 is provided at the front part of the main body 11 and behind the first extension part 12. In this way, when the operator holds the handle 10 for surgical operations, the index finger can extend into the finger sleeve channel formed between the finger set 2 and the sleeve body 1, and then operate the knob 101 with the index finger, so as to conveniently switch the angle of the cutting tool 20. At the same time, the reset of the index finger will bring the corresponding part of the handle protective cover back to its original position, avoiding the appearance of wrinkles that affect surgical operations, and also avoiding the need for the cooperation of the other hand to pull the wrinkled part back to its original position, which may affect the smooth progress of the operation.

[0038] Specifically, the finger kit 2 extends in the vertical direction. The upper end and the lower end of the finger kit 2 are respectively fixedly attached to the sleeve body 1. The finger kit 2 is in the shape of a strip-like band. The lower front part of the main body 11 also has a positioning part 17, which is configured to receive one handle of the handle 10, and the lower end of the finger kit 2 is arranged on the positioning part 17. Since the positions of the above-mentioned handle and the knob 101 are relatively fixed, when the handle 10 is placed into the main body 11, after the above-mentioned handle can be received into the positioning part 17, the positions of the finger kit 2 and the knob 101 can also be relatively fixed, ensuring that when the operator holds the handle 10 for operation, the index finger can cooperate with the finger kit 2 to operate the knob 101.

[0039] Specifically, referring to Figure 1 , Figure 2 As shown, in this embodiment, the lower part of the handle 10 has a gripping handle 103, an operating handle 104 and a positioning handle 102. The gripping handle 103 serves as the main handle of the handle 10 for the operator to hold, and the power cord 30 is also connected to the lower part of the gripping handle 103; the operating handle 104 is used for operation to control operations such as clamping and releasing in the tool 20, and the positioning handle 102 serves as a handle that is less or not operated during the operation. Cooperating it with the positioning part 17 further ensures the good cooperation between the sleeve body 1 and the handle 10 during the operation and is not easily slipped or misaligned.

[0040] In this handle protector, the sleeve body 1 is an integral part made of a disposable plastic film, and it is preferably set to be transparent. The finger kit 2 is made of the same material as the sleeve body 1. It can be integrally formed on the sleeve body 1 or additionally attached to the sleeve body 1; the main sealing member 3, the first sealing member 4 and the drawstring 5 are respectively attached to the sleeve body 1.

[0041] As a disposable product, the handle protector is aseptically packaged. During packaging, after the second extension part 13 is folded along the length direction, the main body part 11 is folded along the length direction and folded relative to the second extension part 13 to form a square shape for packaging and storage.

[0042] During use, it is necessary to unfold the main body part 11 of the handle protector, keep the second extension part 13 in a folded state, first place the handle 10 into the main body part 11, continuously wind the upper part of the main body part 11 in the vertical direction, and then close the main entrance 14 through the main sealing member 3; then insert the tool 20 into the first extension part 12 and cooperate it with the handle 10, and then fold the first sealing member 4 in half to close the first opening 15; then insert one end of the power cord 30 into the second extension part 13 through the second opening 16 and connect it with the handle 10, then unfold the second extension part 13 along the length direction along the power cord 30, and finally tie the drawstring 5 to complete the cooperative connection of the ultrasonic scalpel.

[0043] In summary, the provision of the protective sheath for the ultrasonic scalpel handle of the present utility model enables the handle 10 and the power cord 30 to be fully protected during the operation, avoiding the inconvenience of contamination, cleaning and disinfection caused by blood, tissue fluid, etc. entering the inside of the handle 10. In particular, the operator can also cooperate the index finger with the finger set 2 to rotate the operation knob 101, so as to avoid problems such as inconvenience caused by the wrinkles of the handle protective sheath caused by rotating the operation knob 101 during the operation.

[0044] The above embodiments are only for illustrating the technical concept and features of the present utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it cannot be used to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
