Description

Technical Field

[0001] This utility model relates to the field of laparoscopic surgical equipment technology, and in particular to an ultrasonic scalpel with an additional smoke exhaust device for laparoscopic surgery. Background Technology

[0002] During laparoscopic surgery, an ultrasonic scalpel is used to separate, cut, and coagulate human tissue. This process generates a large amount of smoke. If there is no special smoke extraction device inserted into the abdominal cavity, the smoke will adhere to the camera used in laparoscopic surgery, causing the surgical field of vision to become blurred and affecting the progress of the surgery. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing an ultrasonic scalpel with an additional smoke extraction device for laparoscopic surgery.

[0004] The technical solution of this utility model is implemented as follows:

[0005] This utility model provides an ultrasonic scalpel with an additional smoke extraction device for laparoscopic surgery, the smoke extraction device comprising:

[0006] The smoking tip is detachably mounted on the handle of the ultrasonic scalpel;

[0007] The exhaust pipe has one end connected to the inside of the smoking head and the other end connected to the suction device;

[0008] The cigarette butt has a hollow structure, and several holes are provided on the side wall of the cigarette butt.

[0009] In one embodiment, the distance between the front end of the smoking tip and the ultrasonic scalpel tip is 2cm to 3cm.

[0010] In one embodiment, the smoke exhaust device further includes a bracket, the bottom of which is detachably connected to the blade and the top of which is detachably connected to the smoke exhaust pipe.

[0011] In one embodiment, the holes are formed at the top of the cigarette butt, and the holes are arranged at equal intervals along the length of the cigarette butt.

[0012] In one embodiment, the holes are formed in the sidewall of the cigarette butt, and the holes are arranged at equal intervals along the length of the cigarette butt.

[0013] In one embodiment, the diameter of the hole gradually increases from the inside to the outside of the cigarette holder.

[0014] In one embodiment, a filter screen is also installed inside the cigarette holder, the filter screen covering the holes. This is unnecessary; it is not for absorbing water or tissue.

[0015] In one embodiment, the bottom of the smoking head is a latching part, and the cross-section of the latching part is an arc-shaped structure consistent with the curvature of the blade.

[0016] Let X be the distance from the middle to the top of the tool holder, where X = X1 + X2, and X1 is the distance from the bottom of the latching part to the middle of the tool holder; X2 is the distance from the bottom of the latching part to the bottom of the tool holder.

[0037] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0038] Reference Figure 1 A fume extraction device for an ultrasonic scalpel used in laparoscopic surgery is disclosed. Specifically, the fume extraction device is installed on the handle 40 of the ultrasonic scalpel. The fume extraction device includes a fume extraction head 10, detachably mounted on the handle 40 of the ultrasonic scalpel. The fume extraction head 10 has a hollow structure, and several holes 11 are formed in the side wall of the fume extraction head 10. Figure 1 and Figure 7 As shown, the bottom of the smoking head 10 is a latching part 13. The cross-section of the latching part 13 is an arc-shaped structure that matches the curvature of the blade 40. The latching part 13 is elastic. During installation, the gap between the bottoms of the latching parts 13 needs to be aligned with the top of the blade 40 and latched down. The elastic potential energy of the latching part 13 is used to firmly latch the smoking head 10 onto the blade 40.

[0039] Furthermore, let X be the distance from the middle to the top of the blade shank 40, where X = X1 + X2, and X1 is the distance from the bottom of the latching part 13 to the middle of the blade shank 40; X2 is the distance from the bottom of the latching part 13 to the bottom of the blade shank 40; in the above, X1 = 0.7X. This arrangement allows the latching part 13 to cover at least 80% of the blade shank 40, preventing the smoking head 10 from falling off during use.

[0040] As a further improvement to the above structure, such as Figure 10 As shown, the latching part 13 has a bevel 14 near the tail of the cigarette holder 10. When installing the cigarette holder 10, the user can first latch the bottom part of the bevel 14 onto the blade 40, and then press the front end of the cigarette holder 10 downwards to complete the installation of the cigarette holder 10. Figure 9 As shown, this is to facilitate the quick installation of the cigarette butt 10; if the bevel 14 is not provided, the user can only press the entire cigarette butt 10 downwards, resulting in a large contact area and making installation laborious.

[0041] As a further improvement to the above structure, the distance between the front end of the smoking head 10 and the ultrasonic scalpel head is 2cm to 3cm. If the smoking head 10 is too close to the ultrasonic scalpel head and less than 2cm, it will block the forward view and affect the normal use of the ultrasonic scalpel head. In addition, the high temperature of the ultrasonic scalpel head will cause the smoking head 10 to melt. If the smoking head 10 is too far from the ultrasonic scalpel head and greater than 3cm, it will reduce the smoking efficiency and make it difficult to completely absorb the smoke generated at the ultrasonic scalpel head.

[0042] The smoke exhaust device further includes a smoke exhaust pipe 20, one end of which is connected to the inside of the smoking head 10, and the other end is connected to the suction device of the operating room. The suction device of the operating room will generate negative pressure in the smoke exhaust pipe 20, which will also generate negative pressure in the hollow part inside the smoking head 10, so that the smoke around the smoking head 10 enters the smoking head 10 through the hole 11 and is then extracted through the smoke exhaust pipe 20.

[0043] The smoke extraction device further includes a bracket 30, the length of which is the same as that of the smoke extraction head 10. The bottom of the bracket 30 is detachably connected to the blade 40, and the top is detachably connected to the smoke extraction pipe 20. Figure 1 and Figure 2 As shown, the bracket 30 can ensure that the exhaust pipe 20 is taut along the blade 40, and the exhaust pipe 20 located inside the human body is not easy to bend or move during the operation, thus ensuring the smooth operation of the operation.

[0044] The smoking head 10, the smoke exhaust light 20, and the bracket 30 mentioned above are an integrated device.

[0045] Based on the above structure, this utility model has two embodiments regarding the arrangement of the holes 11:

[0046] In the first embodiment, such as Figure 3 and Figure 4 As shown, holes 11 are formed at the top of the cigarette butt 10, and the holes 11 are arranged at equal intervals along the length of the cigarette butt 10.

[0047] In the second embodiment, such as Figure 5 and Figure 6 As shown, holes 11 are formed on the side wall of the smoking head 10, and the holes 11 are equidistant along the length of the smoking head 10. The diameter of the holes 11 gradually increases from the inside to the outside of the smoking head 10. The larger external opening can provide a larger air intake area, which helps to improve the smoking efficiency, especially in environments where smoke diffuses quickly. The design of being larger on the outside and smaller on the inside can reduce the resistance of air flow, making it easier for air to be drawn in and improving the working efficiency of the smoking device.

[0048] It should be noted that both the first and second embodiments are within the scope of protection of this application.

[0049] The aforementioned smoking head 10, exhaust pipe 20, and support 30 are all disposable devices and will be discarded after the surgery.

[0050] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0051] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
