Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a laparoscope protection device. Background Art

[0002] Laparoscopes are commonly used medical devices in departments such as surgery, thoracic surgery, and gynecology. Laparoscopes are required for laparoscopic cholecystectomy and laparoscopic hepatectomy. Currently, during surgery, the laparoscope needs to be inserted into the body and come into contact with the cavity fluid, which can cause the laparoscope lens to be contaminated by the cavity fluid. Post-operative disinfection of the laparoscope affects the life of the lens and is difficult to disinfect. In addition, the end of the laparoscope is connected to a wiring harness. During surgery, the wiring harness is often wrapped in a film-like protective bag. The film is usually tied to the wiring harness by a connecting rope. However, the connection process of the connecting rope is complicated, the connection effect is unstable, and the use effect is poor. Utility Model Content

[0003] The utility model discloses a laparoscope protection device to improve the above problems.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] Based on the above objectives, the present invention discloses a laparoscope protection device, comprising:

[0006] A laparoscope cover, the laparoscope cover is used to be placed outside the laparoscope;

[0007] a control handle connected to the laparoscope sleeve; and

[0008] A control structure, the control structure includes a first control ring, a second control ring and a clamping block, the first control ring is installed on the control handle, and the first control ring is sleeved outside the laparoscope cover, the clamping block is slidably matched with the control handle, and the clamping block can move relative to the first control ring along the radial direction of the laparoscope cover, the second control ring is rotatably connected to the control handle, and the clamping block is slidably matched with the second control ring, and the second control ring is rotated to make the clamping block move inward or outward along the radial direction of the laparoscope cover.

[0009] The laparoscope protection device disclosed in this embodiment places the laparoscope sleeve in the laparoscope sleeve, and by rotating the second control ring, the clamping block can be driven to move to clamp or loosen the laparoscope sleeve. When the clamping block clamps the laparoscope sleeve, the laparoscope sleeve can be stably fixed to the laparoscope, thereby achieving effective isolation of the laparoscope from the external environment during the operation, avoiding the disinfection problem caused by the contamination of the laparoscope by the cavity fluid, and using the second control ring to achieve quick connection between the laparoscope sleeve and the laparoscope, thereby improving the preparation efficiency of the laparoscope before the operation.

[0010] Optionally, the second control ring is threadedly connected to the control handle, and when the second control ring rotates in a positive direction, the second control ring drives the clamping block to move radially inwardly of the laparoscope sleeve.

[0011] By making the second control ring cooperate with the control handle thread, when the clamping block clamps the laparoscope sleeve to the outside of the laparoscope, the reaction force of the supporting block acts on the thread position, thereby fixing the second control ring and achieving stable clamping of the clamping block.

[0012] Optionally, the control structure further comprises a control rod, the control rod is slidably engaged with the control handle, the control rod can slide relative to the control handle along the axial direction of the laparoscope sleeve, and a first latching tooth is provided on one end of the control rod facing the second control ring;

[0013] A plurality of second latching teeth are provided on a side of the second control ring facing the control rod. The plurality of second latching teeth are arranged in sequence along the circumference of the second control ring. The second latching teeth cooperate with the first latching teeth to fix the second control ring or enable the second control ring to rotate only in one positive direction.

[0014] By using the control block to restrict the second control ring, the stability of the second control ring in controlling the position of the clamping block can be further improved. When release is required, it is only necessary to separate the control rod from the second control ring.

[0015] Optionally, the control structure further includes a spring member, both ends of which are connected to the control handle and the control rod respectively, and the spring member causes the control rod to have a tendency to move toward the second control ring.

[0016] The spring member can be used to maintain the stable contact between the control rod and the second control ring. At this time, the medical staff does not need to pay attention to the position of the control rod at any time, which greatly reduces the physical strength of the medical staff.

[0017] Optionally, the control rod includes a longitudinal rod and a transverse rod, the longitudinal rod is slidably connected to the control handle, the transverse rod is rotatably connected to the longitudinal rod, and the rotation axis of the transverse rod is parallel to the axis of the laparoscope sleeve;

[0018] A limiting groove is provided on the control handle, and the limiting groove extends along the circumference of the control handle. When the cross bar is aligned with the limiting groove, the cross bar can be rotated into the limiting groove to fix the longitudinal bar.

[0019] When the laparoscope sleeve needs to be separated from the laparoscope, the control rod needs to be loosened first. After the control rod is set to the above structure, it is only necessary to separate the control rod from the second control ring first, then slide the control rod until the cross bar is aligned with the limit groove, and then rotate the cross bar into the limit groove. This allows the control rod to be stably separated from the second control ring without the medical staff having to continuously operate the position of the control rod.

[0020] Optionally, a first guide groove is provided on the first control ring, the first guide groove extends radially along the first control ring, and the clamping block is in sliding engagement with the first guide groove.

[0021] When the second control ring pushes the clamping block to move, the clamping block can only move along the first guide groove direction, so that the clamping block can stably move along the radial direction of the first control ring, thereby stably fixing the laparoscope sleeve and the laparoscope.

[0022] Optionally: a second guide groove is provided on the second control ring at a position corresponding to the first guide groove, and the second guide groove is provided in an arc shape on the second control ring. The clamping block slides in cooperation with the second guide groove so that when the second control ring rotates, the clamping block can be driven to move radially inward or outward along the laparoscope sleeve.

[0023] The second guide groove cooperates with the first guide groove to enable the clamping block to move radially along the first control ring when the second control ring rotates. Of course, the above structure is only one implementation of this embodiment. In other implementations, other structures can be provided on the second control ring to enable the clamping block to move along the first guide groove.

[0024] Optionally, the control rod, the second control ring and the first control ring are arranged in sequence along the height direction of the control handle.

[0025] Such installation can make the overall structure more compact and more convenient to operate.

[0026] Optionally: the clamping block is located on the side of the first control ring away from the second control ring, the first guide groove passes through the first control ring along the axial direction of the first control ring, and a guide rod is provided on the clamping block. The cross-section of the guide rod is circular, and the guide rod passes through the first guide groove and is inserted into the second guide groove.

[0027] Since the second guide groove is arc-shaped and the clamping block only moves relative to the second control ring without rotating during the rotation of the second control ring, making the cross section of the guide rod circular can better cooperate with the second control ring.

[0028] Optionally, the inner wall of the clamping block is configured to be arc-shaped, and the inner diameter of the clamping block gradually decreases in a direction away from the first control ring.

[0029] In this way, after the clamping block abuts against the laparoscope sleeve, the contact area between the clamping block and the laparoscope sleeve is small, thereby better fixing the laparoscope sleeve and the laparoscope.

[0030] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0032] The laparoscope protection device disclosed in this embodiment places the laparoscope sleeve in the laparoscope sleeve, and by rotating the second control ring, the clamping block can be driven to move to clamp or loosen the laparoscope sleeve. When the clamping block clamps the laparoscope sleeve, the laparoscope sleeve can be stably fixed to the laparoscope, thereby achieving effective isolation of the laparoscope from the external environment during the operation, avoiding the disinfection problem caused by the contamination of the laparoscope by the cavity fluid, and using the second control ring to achieve quick connection between the laparoscope sleeve and the laparoscope, thereby improving the preparation efficiency of the laparoscope before the operation.

[0049] Example:

[0050] See Figures 1 to 6 The embodiment of the utility model discloses a laparoscope protection device, which includes a laparoscope cover 100, a control handle 200 and a control structure 300. The laparoscope cover 100 is used to be mounted outside the laparoscope. The control handle 200 is connected to the laparoscope cover 100. The control structure 300 includes a first control ring 330, a second control ring 310 and a clamping block 340. The first control ring 330 is mounted on the control handle 200 and is mounted outside the laparoscope cover 100. The clamping block 340 is slidably engaged with the control handle 200. The clamping block 340 can move relative to the first control ring 330 along the radial direction of the laparoscope cover 100. The second control ring 310 is rotatably connected to the control handle 200 and is slidably engaged with the second control ring 310. The second control ring 310 is rotated to move the clamping block 340 inward or outward along the radial direction of the laparoscope cover 100.

[0051] The laparoscope protection device disclosed in this embodiment places the laparoscope sleeve in the laparoscope sleeve 100, and by rotating the second control ring 310, the clamping block 340 can be driven to move to clamp or loosen the laparoscope sleeve 100. When the clamping block 340 clamps the laparoscope sleeve 100, the laparoscope sleeve 100 can be stably fixed to the laparoscope, thereby achieving effective isolation of the laparoscope from the external environment during the operation, avoiding the disinfection problem caused by the contamination of the laparoscope by the cavity fluid, and using the second control ring 310 to achieve quick connection between the laparoscope sleeve 100 and the laparoscope, thereby improving the efficiency of the preparation of the laparoscope before the operation.

[0052] In one embodiment, the second control ring 310 is threadedly connected to the control handle 200 . When the second control ring 310 rotates in a positive direction, the second control ring 310 drives the clamping block 340 to move radially inwardly of the laparoscope sleeve 100 .

[0053] The screwing of the second control ring 310 with the control handle 200 can make the second control ring 310 be fixed by the reaction force of the clamping block 340 when the clamping block 340 clamps the endoscope cover 100 to the outside of the endoscope, so as to realize the stable clamping of the clamping block 340.

[0054] In an embodiment, the control structure 300 further comprises a control rod 320, the control rod 320 is in sliding fit with the control handle 200, the control rod 320 can slide relative to the control handle 200 along the axial direction of the endoscope cover 100, and one end of the control rod 320 is provided with a first clamping tooth.

[0055] The side of the second control ring 310 facing the control rod 320 is provided with a plurality of second clamping teeth, the plurality of second clamping teeth are sequentially arranged along the circumferential direction of the second control ring 310, and the second clamping teeth cooperate with the first clamping tooth to fix the second control ring 310 or make the second control ring 310 only rotate in one positive direction.

[0056] The limitation of the second control ring 310 by the control block can further improve the stability of the position control of the clamping block 340 by the second control ring 310, and when it is needed to be loosened, the control rod 320 and the second control ring 310 only need to be separated.

[0057] In an embodiment, the control structure 300 further comprises a spring member 350, two ends of the spring member 350 are connected with the control handle 200 and the control rod 320 respectively, and the spring member 350 makes the control rod 320 have a tendency to move towards the second control ring 310.

[0058] The use of the spring member 350 can keep the stable abutment of the control rod 320 and the second control ring 310, so that the medical staff does not need to pay attention to the position of the control rod 320 at any time, and the physical strength of the medical staff is greatly reduced.

[0059] In an embodiment, the control rod 320 comprises a vertical rod 321 and a horizontal rod 322, the vertical rod 321 is in sliding connection with the control handle 200, the horizontal rod 322 is in rotational connection with the vertical rod 321, and the rotational axis of the horizontal rod 322 is parallel to the axis of the endoscope cover 100.

[0060] A limiting groove is arranged on the control handle 200, the limiting groove extends along the circumferential direction of the control handle 200, and when the horizontal rod 322 is aligned with the limiting groove, the horizontal rod 322 can be rotated into the limiting groove to fix the vertical rod 321.

[0061] When it is needed to separate the endoscope cover 100 from the endoscope, the control rod 320 needs to be loosened first, and after the control rod 320 is set to the above structure, it is only needed to separate the control rod 320 from the second control ring 310 first, and then slide the control rod 320 to the horizontal rod 322 aligns with the limiting slot, and then rotates the horizontal rod 322 into the limiting slot, so that the control rod 320 and the second control ring 310 can be stably separated without the need for medical staff to continuously operate the position of the control rod 320.

[0062] In an embodiment, the first control ring 330 is provided with a first guide slot 331 extending along the radial direction of the first control ring 330, and the clamping block 340 is in sliding fit with the first guide slot 331.

[0063] When the second control ring 310 pushes the clamping block 340 to move, the clamping block 340 can only move along the direction of the first guide slot 331, so that the clamping block 340 can stably move along the radial direction of the first control ring 330, and in turn can stably fix the endoscope cover 100 with the endoscope.

[0064] In an embodiment, the second control ring 310 is provided with a second guide slot 311 at a position corresponding to the first guide slot 331, the second guide slot 311 is arranged in an arc shape on the second control ring 310, and the clamping block 340 is in sliding fit with the second guide slot 311 so that the second control ring 310 can drive the clamping block 340 to move inward or outward along the radial direction of the endoscope cover 100 when the second control ring 310 rotates.

[0065] The second guide slot 311 cooperates with the first guide slot 331 to realize the movement of the clamping block 340 along the radial direction of the first control ring 330 when the second control ring 310 rotates. Of course, the above structure is only one embodiment of the present embodiment, and in other embodiments, other structures can be provided on the second control ring 310 to move the clamping block 340 along the first guide slot 331.

[0066] In an embodiment, the control rod 320, the second control ring 310 and the first control ring 330 are arranged in sequence along the height direction of the control handle 200.

[0067] Such installation can make the overall structure more compact and more convenient to operate.

[0068] In an embodiment, the clamping block 340 is located on the side of the first control ring 330 away from the second control ring 310, the first guide slot 331 penetrates through the first control ring 330 along the axis direction of the first control ring 330, the clamping block 340 is provided with a guide rod 341, the cross section of the guide rod 341 is circular, and the guide rod 341 is inserted into the second guide slot 311 after penetrating through the first guide slot 331.

[0069] Since the second guide groove 311 is arc-shaped, and the clamping block 340 only moves relative to the second control ring 310 and does not rotate during the rotation of the second control ring 310, making the cross section of the guide rod 341 circular can better cooperate with the second control ring 310.

[0070] In one embodiment, the inner wall of the clamping block 340 is configured to be arc-shaped, and the inner diameter of the clamping block gradually decreases in a direction away from the first control ring 330 .

[0071] In this way, after the clamping block 340 abuts against the laparoscope sleeve 100 , the contact area between the clamping block 340 and the laparoscope sleeve 100 is small, thereby better fixing the laparoscope sleeve 100 and the laparoscope.

[0072] In one embodiment of the present embodiment, the clamping blocks 340 can be set to be multiple, and accordingly, the first guide grooves 331 and the second guide grooves 311 also need to be set to be multiple, and the number of the first guide grooves 331 and the second guide grooves 311 is equal to the number of the clamping blocks 340. The multiple clamping blocks 340 can ensure that the force on the laparoscope cover 100 is more uniform, thereby making the connection between the laparoscope cover 100 and the laparoscope more stable.

[0073] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
