Description

Technical Field

[0001] This invention relates to the field of treatment tool technology, and specifically to a disposable endoscope puncture device. Background Technology

[0002] In the field of modern medicine, endoscopy is a revolutionary advancement that allows doctors to directly observe lesions inside the patient's body without performing large-incision surgery. Through a trocar, the endoscope can reach hard-to-reach areas inside the body and transmit high-definition images to a display screen in real time, providing doctors with an intuitive and comprehensive view of the inside of the body. This greatly improves the accuracy of diagnosis, postoperative aesthetics, and treatment efficiency.

[0003] However, during use, the endoscope is easily fogged or contaminated due to temperature differences between the inside and outside of the body, as well as internal tissues and fluids. This prevents the endoscope from capturing clear images, affecting the surgeon's surgical outcome and progress. Currently, the common method to remove fog or stains from the endoscope is rinsing. For example, Chinese invention patent application number CN218304859U discloses an endoscope sheath that allows for the introduction of rinsing fluid through an inlet valve to clean the operating part, and an outlet valve to drain the contaminated fluid. However, this design, with the through-hole located near the sheath base, cannot prevent liquid from flowing out through the gap between the sheath and the endoscope, and the continuous liquid flow at the front of the image acquisition unit still cannot prevent interference with the endoscope's image acquisition effect. Furthermore, residual cleaning fluid from the laparoscope entering the abdominal cavity can lead to residual fluid accumulation and potentially cause other complications. Summary of the Invention

[0004] The purpose of this invention is to provide a disposable endoscope cleaning and puncture device, which solves the problem that in the prior art, most puncture devices used with endoscopes are cleaned by rinsing, which can easily lead to residual cleaning agent on the laparoscope entering the abdominal cavity and causing fluid accumulation in the abdominal cavity, which can easily cause other complications.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A disposable endoscope cleaning and puncture device includes a cannula and a cannula seat disposed at the upper end of the cannula. A puncture head is disposed at the lower end of the cannula. One side of the upper end of the puncture head is connected to one side of the lower end of the cannula via a spring. An elastic groove is recessed on the upper side of the puncture head, and a spring is disposed in the elastic groove. A cleaning plate is installed on the upper end of the spring, and the cleaning plate is close to the other side of the upper end of the puncture head away from the spring.

[0006] A further technical solution is that the lower end of the cannula is recessed with an upper connecting hole, and the upper end of the puncture head is recessed with a lower connecting hole corresponding to the position of the upper connecting hole. The upper end of the spring is installed in the upper connecting hole, and the lower end of the spring is installed in the lower connecting hole.

[0007] A further technical solution is that the lower end of the sleeve is inclined downward from one side with the upper connecting hole to the other side to form a first inclined surface, and the upper end of the puncture head is set as a second inclined surface that cooperates with the first inclined surface.

[0008] A further technical solution is that the outer wall of the puncture head away from the spring is recessed to form a fitting groove, and the lower end of the sleeve is provided with a fitting plate that matches the fitting groove on the side away from the spring.

[0009] A further technical solution is that a sliding strip hole is vertically provided near the lower end of the spring, and an insertion hole communicating with the lower connecting hole is provided on the outer wall of the piercing head. A pin is locked in the insertion hole, and the pin passes into the lower connecting hole and slides up and down in the lower connecting hole and the sliding strip hole. A groove is provided in the recess of the lower groove wall of the fitting groove, and a locking block is provided on the lower side of the fitting plate at the position of the corresponding groove.

[0010] A further technical solution is to have a through gap formed in the lower end of the second slope.

[0011] A further technical solution is that a base is installed at the lower end of the lens cleaning plate, and a connecting rod is vertically arranged on the lower side of the base. The upper end of the spring is sleeved on the outer wall of the connecting rod and contacts the lower side of the base. A sliding groove is vertically arranged on the side of the base facing the spring. The wall of the lower connecting hole has a connecting hole that communicates with the elastic groove on the side away from the insertion hole. The connecting hole communicates with the sliding groove. One end of the pin is locked in the insertion hole, and the other end passes through the sliding hole and the connecting hole in sequence and is slidably set in the sliding groove.

[0012] A further technical solution is that the upper end of the lens cleaning plate is set as a third inclined surface, which gradually slopes upward from the side facing the spring to the other side, and a fourth inclined surface is set at the upper end of the second inclined surface, which slopes downward from the connection point with the second inclined surface to the other side.

[0013] A further technical solution is to install a wiping layer on the upper part of the lens cleaning plate.

[0014] Compared with the prior art, the beneficial effects of this invention are: 1. In abdominal surgery, in order to reduce blind spots, the endoscope generally adopts an inclined lens. When the endoscope is inserted from the cannula seat and then moves down along the cannula, it will press against the cleaning plate. When the inclined lens abuts against the cleaning plate, the spring contact method will cause the puncture head to bend the spring contact to deviate from the cannula, squeezing the puncture head to one side, thereby allowing the endoscope to pass through the cannula and capture a high-definition image of the abdominal cavity. When the endoscope image is blurry, the endoscope can be used to capture a high-definition image of the abdominal cavity. 1. By pulling the endoscope up and down, it can be repeatedly inserted and withdrawn from the cannula, allowing the endoscope to contact the cleaning plate and thus scrape away dirt or water vapor from its surface; 2. With the help of a spring, the cleaning plate and endoscope are kept in constant contact during the contact process, and a certain amount of pressure is applied to clean the endoscope; 3. This application allows for multiple cleanings of the endoscope throughout the entire surgical procedure, is simple to operate, and does not require removing the endoscope, thus avoiding the possibility of other contamination.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be 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 and not intended to limit the invention.

[0027] Figures 1 to 10 The diagram shown is a schematic representation of an embodiment.

[0028] Example 1: A disposable laparoscopic cleaning and puncture device includes a cannula 1 and a cannula seat 2 located at the upper end of the cannula 1. A puncture head 3 is located at the lower end of the cannula 1. One side of the upper end of the puncture head 3 is connected to one side of the lower end of the cannula 1 via a spring 4. An elastic groove 5 is recessed on the upper side of the puncture head 3, and a spring 6 is installed within the elastic groove 5. A cleaning plate 7 is mounted on the upper end of the spring 6, located near the upper end of the puncture head 3 and away from the spring 4. In abdominal surgery, to reduce blind spots, the endoscope generally uses an inclined lens, such as... Figure 7-10As shown, when the endoscope is inserted from the cannula seat 2 and moves downwards along the cannula 1, it will press against the cleaning plate 7. When the tilted lens comes into contact with the cleaning plate 7, the spring 4 connects the endoscope, causing the puncture head 3 to bend and deviate from the cannula 1, squeezing the puncture head 3 to one side, thus allowing the endoscope to pass through the cannula 1 and capture a high-definition image of the abdominal cavity. When the endoscope image becomes blurry, pulling the endoscope up and down allows it to repeatedly enter and exit the cannula 1, maintaining contact with the cleaning plate 7. The cleaning plate 7 then scrapes away dirt or water vapor from the endoscope surface. The spring 6 ensures that the cleaning plate 7 remains in contact with the endoscope during contact and provides pressure to clean it. This application allows for multiple cleanings of the endoscope throughout the surgical procedure, simplifying the operation and eliminating the need to remove the endoscope, thus avoiding potential contamination. The cannula seat 2 can adopt a conventional structure or an existing structure in the prior art. A duckbill valve 27 is set inside the cannula seat 2. The duckbill valve 27 can seal the inside and outside of the abdominal cavity. After the endoscope is inserted, the duckbill valve 27 can fit against the outer wall of the endoscope to prevent gas from leaking from the inner wall of the endoscope.

[0029] The lower end of the cannula 1 is recessed with an upper connecting hole 8, and the upper end of the puncture head 3 is recessed with a lower connecting hole 9 corresponding to the upper connecting hole 8. The upper end of the spring piece 4 is installed in the upper connecting hole 8, and the lower end of the spring piece 4 is installed in the lower connecting hole 9. By providing the upper connecting hole 8 and the lower connecting hole 9, the upper and lower ends of the spring piece 4 can be fixed, thereby connecting the puncture head 3 to the lower end of the cannula 1.

[0030] The lower end of the cannula 1 slopes downwards from the side with the upper connecting hole 8 to the other, forming a first inclined surface 10. The upper end of the puncture head 3 is configured as a second inclined surface 11 that mates with the first inclined surface 10. By setting the first inclined surface 10 and the second inclined surface 11, when the puncture head 3 and the cannula 1 are in a straight line, the upper end of the puncture head 3 and the lower end of the cannula 1 can be brought into contact with each other using the first inclined surface 10 and the second inclined surface 11. Furthermore, when the endoscope pushes the puncture head 3 to one side, the second inclined surface 11 can be used to bring it into contact with the endoscope, reducing the angle of deviation of the puncture head 3, i.e., the angle between the puncture head 3 and the cannula 1.

[0031] The outer wall of the puncture head 3, away from the spring 4, has a recessed fitting groove 12. The lower end of the cannula 1, away from the spring 4, has a fitting plate 13 that matches the fitting groove 12. By providing the fitting groove 12 and the fitting plate 13, when the puncture head 3 and the cannula 1 are aligned, the fitting plate 13 engages with the fitting groove 12, improving the overall integrity of the cannula 1 and the puncture head 3. Simultaneously, the fitting plate 13 provides lateral support to the endoscope exiting the cannula 1, preventing the endoscope from being pressed, squeezed, or bent by the puncture head 3 and the spring 4, thus avoiding difficulty in controlling the endoscope.

[0032] The spring clip 4 has a vertically arranged sliding strip hole 14 near its lower end. The outer wall of the puncture head 3 has an insertion hole 15 that communicates with the lower connecting hole 9. A pin 16 is inserted into the insertion hole 15, and the pin 16 passes into the lower connecting hole 9 and slides vertically connected with the sliding strip hole 14 within the lower connecting hole 9. The lower groove wall of the fitting groove 12 has a recessed slot 17, and the lower side of the fitting plate 13 has a locking block 18 at the position corresponding to the slot 17. Before using the endoscope, the puncture head 3 and the cannula 1 need to be inserted into the patient's abdominal cavity. During the puncture, in order to prevent the puncture head 3 and the cannula 1 from shifting, the locking slot 17 and the locking block 18 are used to fix the fitting plate 13 and the fitting groove 12 together, thereby fixing the puncture head 3 and the cannula 1 in conjunction with the connection position of the spring clip 4. When the endoscope is used for the first time, it moves downward against the cleaning plate 7. When the compressed spring 6 reaches its lowest point, it moves the puncture head 3 downward, causing the retaining block 18 to separate from the retaining groove 17. This allows the puncture head 3 to deviate around the spring 4, allowing the endoscope to pass through the cannula 1. With the help of the sliding strip hole 14 and the pin 16, the puncture head 3 can slide and connect with the pin 16 during the first use, allowing it to move downward a certain distance.

[0033] The lower end of the second inclined surface 11 is recessed to form a through notch 19. By setting the through notch 19, it can further cooperate with the second inclined surface 11, and when the endoscope passes through the cannula 1, the through notch 19 can be used to fit against the outer wall of the endoscope to reduce the angle of deviation of the puncture head 3.

[0034] A base 20 is installed at the lower end of the lens cleaning plate 7. A connecting rod 21 is vertically arranged on the lower side of the base 20. The upper end of the spring 6 is sleeved on the outer wall of the connecting rod 21 and contacts the lower side of the base 20. A sliding groove 22 is vertically arranged on the side of the base 20 facing the spring 4. A connecting hole 23 is provided on the side of the lower connecting hole 9 away from the insertion hole 15, which communicates with the elastic groove 5. The connecting hole 23 communicates with the sliding groove 22. One end of the pin 16 is locked in the insertion hole 15, and the other end passes through the sliding groove hole 14 and the connecting hole 23 in sequence, and then slides in the sliding groove 22. By setting the base 20, the outer wall of the base 20 can fit against the groove wall of the elastic groove 5, so that the base 20 can drive the lens cleaning plate 7 to move up and down without tilting or shaking. The connecting rod 21 can connect the upper end of the spring 6 to the lower end of the base 20. The pin 16 is fixed by the insertion hole 15 and the connecting hole 23 and will not move. The spring piece 4 can slide up and down with the pin 16 through the sliding strip hole 14. The sliding strip groove 22 can guide the base 20 when it moves up and down, making the up and down movement of the base 20 smoother.

[0035] The upper end of the endoscope cleaning plate 7 is configured with a third inclined surface 24, which gradually slopes upward from one side towards the spring 4 to the other. A fourth inclined surface 25 is provided at the upper end of the second inclined surface 11, which slopes downward from its connection point with the second inclined surface 11 to the other side. By providing the third inclined surface 24, the contact area between the upper end of the endoscope cleaning plate 7 and the endoscope is reduced during cleaning, thus improving the cleaning effect. Additionally, the cleaned materials or water mist are guided to the elastic groove 5 and accumulated there, preventing residue from remaining in the patient's abdominal cavity. The fourth inclined surface 25 provides sufficient space for movement at the connection point between the puncture head 3 and the cannula 1 via the spring 4, allowing for sufficient exposure of the spring 4 for bending.

[0036] A wiping layer 26 is installed on the upper end of the lens cleaning plate 7. By setting the wiping layer 26, stains on the endoscope lens can be removed more effectively. The wiping layer 26 can be made of absorbent cotton or non-absorbent silicone, etc.

[0037] Although the invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
