Description

Technical Field

[0001] The utility model relates to medical equipment, and more particularly to a device for cleaning the inner wall of a laparoscope puncture sheath tube based on a da Vinci robot surgery. Background Art

[0002] In the medical field, thorough cleaning of the inner wall of laparoscopic puncture sheaths used in da Vinci robotic surgery, particularly during minimally invasive surgery and interventional procedures, is a crucial task. Traditional cleaning methods often rely on manual labor, which is not only inefficient but also difficult to reach every corner of the lumen, leaving behind residual blood, tissue fragments, and other contaminants, increasing the risk of postoperative infection. Furthermore, traditional cleaning tools struggle with the small, complex structures of the lumen.

[0003] Therefore, the market urgently needs an efficient, convenient device that can fully penetrate the inner wall of the laparoscopic sheath based on the da Vinci robotic surgery to improve the efficiency and safety of the surgery and reduce postoperative complications. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an improved device for cleaning the inner wall of a laparoscopic puncture sheath tube based on Da Vinci robotic surgery.

[0005] The technical solution adopted by the present invention to solve the technical problem is: constructing a laparoscopic puncture sheath inner wall cleaning device based on Da Vinci robotic surgery, comprising an outer sheath, an inner sheath inserted into the outer sheath and movable axially relative to the outer sheath, a push-pull mechanism, and a cleaning component connected to the other end of the inner sheath, wherein the cleaning component is configured to have at least tissue fluid adsorption properties and contraction and expansion properties;

[0006] The push-pull mechanism includes a push-pull button connected to one end of the inner sheath tube and extending out of the outer sheath tube, and the push-pull button is configured to move in a first direction under the action of an external force, pushing the inner sheath tube to move axially outward in the inner cavity of the outer sheath tube, thereby causing the cleaning component to move out of the inner cavity of the outer sheath tube and expand radially outward; and the push-pull button slides in a second direction under the action of an external force, driving the inner sheath tube to move axially toward the inner cavity of the outer sheath tube, so that the cleaning component is in a compressed state radially confined in the inner cavity of the outer sheath tube.

[0007] Further, it is preferred that the cleaning member is at least partially made of sponge.

[0008] Furthermore, it is preferred that the cleaning component includes a brush portion provided at the proximal end and a sponge portion connected to the brush portion.

[0009] Furthermore, it is preferred that the inner sheath tube and / or the outer sheath tube is made of a material having a developable property, or the inner sheath tube and / or the outer sheath tube is coated with a developable layer.

[0010] Furthermore, it is preferred that a synovial membrane is provided on the inner wall surface of the outer sheath tube, and the inner surface of the synovial membrane is smooth.

[0011] Furthermore, it is preferred that a guide rail for guiding the push-pull button is axially provided on the outer sheath tube, the push-pull button extends out of the outer sheath tube through the guide rail, and the push-pull button moves along the extension direction of the guide rail.

[0012] Furthermore, it is preferred that the push-pull mechanism further includes a locking piece, and a locking hole matching the locking piece is provided in the inner sheath tube.

[0013] Furthermore, preferably, the push-pull mechanism also includes a positioning buckle arranged outside the outer sheath tube, and the positioning buckle is arranged at the extreme position of the push-pull button moving along the first direction. When the cleaning component is moved out of the inner cavity of the outer sheath tube and expands radially outward, the push-pull button is engaged with the positioning buckle to limit the push-pull button from continuing to move along the first direction.

[0015] 1. Comprehensive cleaning: The expanded state of the cleaning component can fully contact and clean every corner of the inner wall of the lumen, effectively removing pollutants such as blood and tissue fragments.

[0016] 2. Efficient and convenient: The cleaning components can be expanded and compressed through simple operation of the push-pull mechanism, which greatly improves the cleaning efficiency and convenience of use.

[0017] 3. Safe and reliable: The tissue fluid adsorption characteristics and shrinkage and expansion design of the cleaning components ensure the safety and reliability of the cleaning process.

[0018] 4. Strong adaptability: It is suitable for a variety of lumen structures of different sizes and shapes and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To further illustrate the technical means and technical effects of the present invention, preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0027] Figures 1-6 Several preferred embodiments of the present invention's laparoscopic puncture sheath inner wall cleaning device for da Vinci robotic surgery are shown. This device can be used to clean the inner wall of a laparoscopic puncture sheath during da Vinci robotic surgery, facilitating cleaning operations. This device features a simple structure, easy operation, and high efficiency, achieving comprehensive, efficient, and safe cleaning.

[0028] A laparoscopic puncture sheath inner wall cleaning device based on da Vinci robotic surgery includes an outer sheath 10, an inner sheath 20 that is inserted into the outer sheath 10 and can move axially relative to the outer sheath 10, a push-pull mechanism 30, and a cleaning component 40 connected to the other end of the inner sheath 20, wherein the cleaning component 40 is configured to have at least the characteristics of adsorbing tissue fluid and shrinking and expanding. The outer sheath 10 can be an elongated tubular structure with two through-holes, a diameter of 6mm, and a length of 25cm. A movement space for the inner sheath 20 and the cleaning component 40 is formed in the inner cavity, and its outer diameter matches the inner wall of the laparoscopic puncture sheath to achieve cleaning of the inner wall. The inner sheath 20 is inserted into the outer sheath 10 and can move axially relative to the outer sheath 10. The extension and retraction of the cleaning component 40 are achieved by driving the push-pull mechanism 30.

[0029] Among them, the push-pull mechanism 30 includes a push-pull button 31 connected to one end of the inner sheath tube 20 and extending out of the outer sheath tube 10. The push-pull button 31 is configured to move in a first direction under the action of an external force, pushing the inner sheath tube 20 to move axially outward in the inner cavity of the outer sheath tube 10, thereby causing the cleaning component 40 to move out of the inner cavity of the outer sheath tube 10 and expand radially outward, its diameter or size becomes larger, and after radial outward expansion, it can clean the inner wall of the puncture device / puncture card and adsorb liquid tissue. And the push-pull button 31 slides in a second direction under the action of an external force. The second direction is the direction opposite to the first direction, driving the inner sheath tube 20 to move axially toward the inner cavity of the outer sheath tube 10, so that the cleaning component 40 is in a compressed state radially confined in the inner cavity of the outer sheath tube 10, thereby achieving storage and facilitating the removal of the entire device.

[0030] Furthermore, in some preferred embodiments, the cleaning component 40 is at least partially made of sponge, which has excellent tissue fluid adsorption properties and shrinkage and expansion properties. It can clean the inner wall of the puncture device / puncture card well while adsorbing liquid tissue to achieve clean cleaning without residue.

[0031] Furthermore, in a more preferred embodiment, the cleaning component 40 includes a brush portion 41 disposed at the proximal end and a sponge portion 42 connected to the brush portion 41. The proximal end here refers to the end closest to the operator. The sponge, with its excellent tissue fluid absorption and shrinkage and expansion properties, can initially absorb liquid and small tissue fragments for initial cleaning. The proximal brush portion 41 then enhances the cleaning effect on the inner wall of the puncture device / card, achieving a thorough and residue-free cleaning. Of course, the cleaning component 40 can also consist of a single sponge portion 42.

[0032] In a specific embodiment, the inner sheath tube 20 and / or the outer sheath tube 10 are made of a material having a developing property, or are coated with a developing layer on the outer surface of the inner sheath tube 20 and / or the outer sheath tube 10. For example, the inner sheath tube 20 and / or the outer sheath tube 10 are made of stainless steel, so that the inner sheath tube 20 and / or the outer sheath tube 10 can be imaged under an imaging system, thereby knowing their respective positions and determining whether they are in place.

[0033] Furthermore, the inner wall surface of the outer sheath 10 is preferably provided with a synovial film, the inner surface of the synovial film being smooth, so that the outer sheath 10 and the inner sheath 20 have good sliding properties. Furthermore, the synovial film is preferably a PTFE film, which has low friction and slides smoothly with the inner sheath 20.

[0034] Furthermore, preferably, a guide rail is provided axially on the outer sheath 10 for guiding the push-pull button 31. The push-pull button 31 extends out of the outer sheath 10 through the guide rail and moves along the extension direction of the guide rail. Under the action of an external force, the push-pull button 31 moves along the guide rail in a first direction and reaches an extreme position at one end of the guide rail, indicating that the inner sheath 20 is pushed into place. At this time, the cleaning component 40 is completely removed from the inner cavity of the outer sheath 10 and expands radially outward, increasing in diameter or size, thereby cleaning the inner wall of the puncture device / puncture card and adsorbing liquid tissue. After cleaning is completed, the push-pull button 31 moves in the second direction along the guide rail under the action of external force, and moves to the extreme position at the other end of the guide rail, indicating that the inner sheath tube 20 is pulled into place. At this time, the cleaning component 40 is completely returned from the outside of the outer sheath tube 10 to the inner cavity, so that the cleaning component 40 is in a compressed state radially restricted in the inner cavity of the outer sheath tube 10, thereby realizing storage and facilitating the removal of the entire device.

[0035] Furthermore, it is preferred that the push-pull mechanism 30 further includes a locking member, and a locking hole matching the locking member is provided in the inner sheath tube 20. When the inner sheath tube 20 is pushed into place, the cleaning component 40 expands and unfolds, and the locking member is buckled into the locking hole in the inner sheath tube 20 to fix the position of the inner sheath tube 20.

[0036] In a specific embodiment, the cleaning device further includes a positioning buckle 32 disposed outside the outer sheath 10, the positioning buckle 32 being disposed at the extreme position of the push-pull button 31 moving in the first direction. When the cleaning component 40 is removed from the inner cavity of the outer sheath 10 and radially expands outward, the push-pull button 31 is engaged in the positioning buckle 32, thereby restricting the push-pull button 31 from continuing to move in the first direction. More specifically, the positioning buckle 32 is disposed at the upper end of the guide rail. The positioning buckle 32 is a buckle that matches the push-pull button 31, such as a C-type buckle. The setting of the positioning buckle 32 realizes a positioning effect on the one hand. When the push-pull button 31 is engaged in the positioning buckle 32, it indicates that the cleaning component 40 is removed from the inner cavity of the outer sheath 10 and radially expands outward, thereby achieving a cleaning effect. On the other hand, the setting of the positioning buckle 32 plays a fixing role, preventing the cleaning component 40 from being recovered into the outer sheath 10 during the cleaning process.

[0037] Furthermore, it is preferred that the cleaning component 40 is in an umbrella-like, cloud-like, or column-like state when unfolded, so that it can fully contact and clean the inner wall of the puncture device / puncture card.

[0038] Through the above-mentioned specific implementation methods, the laparoscopic puncture sheath inner wall cleaning device based on Da Vinci robot surgery of the present invention can achieve efficient, convenient and comprehensive cleaning effects, providing strong support for minimally invasive surgery and interventional treatment in the medical field.

[0039] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
