[0035] The following combination Figure 1-3 The utility model is described in further detail.

[0036] Example 1

[0037] Reference Figure 1-3 As shown, this embodiment provides a medical laparoscope heat preservation device, comprising:

[0038] A cylinder 1, wherein an entrance for the laparoscope to enter is provided on the upper surface of the cylinder 1;

[0039] A rubber sealing strip 2, wherein any end of the rubber sealing strip 2 is arranged on the upper surface of the barrel 1 near the inlet through a positioning pin 3, and the end of the rubber sealing strip 2 away from the positioning pin 3 is arranged in a clockwise or counterclockwise direction around the inlet to form a fixing hole 21 for fixing the laparoscope tube. When the rubber sealing strip 2 surrounds and fixes the laparoscope tube, the rubber sealing strip 2 shields the gap between the inlet on the upper surface of the barrel 1 and the laparoscope tube;

[0040] The adjusting mechanism 4 includes a supporting ring 41 coaxially rotatably arranged on the upper surface of the cylinder 1, and an adjusting ring 42 coaxially and rotatably sleeved outside the supporting ring 41. The inner surface of the adjusting ring 42 is connected to the end of the rubber sealing strip 2 away from the positioning pin 3 through a connecting rod 43. The supporting ring 41 is provided with a clearance opening for the connecting rod 43 to pass through.

[0041] Specifically, a plurality of clamping blocks are provided at the lower end of the inner side surface of the adjusting ring 42 in the vertical direction, and a number of clamping grooves for clamping the clamping blocks are the same as the number of the clamping blocks on the outer surface of the supporting ring 41 , and the clamping blocks can be slidably disposed in the clamping grooves.

[0042] Specifically, a heater for heating the cavity mirror is provided at the bottom end of the inner surface of the cylinder 1 .

[0043] The heating and heat preservation of the cavity mirror extending into the cylinder 1 is achieved by the heater.

[0044] In one of the embodiments, the heating and heat preservation of the laparoscope inserted into the barrel 1 can be achieved by injecting sterile hot water into the barrel 1 instead of using a heater.

[0045] In order to achieve the locking of the adjusting mechanism 4, as a further improvement, a locking mechanism 5 is also included, which includes an extension block 51 vertically arranged on the upper surface of the cylinder 1 and arranged in the support ring 41, and a compression spring 52 is horizontally extended in the direction away from the entrance at one end of the extension block 51 away from the cylinder 1, and a locking portion 53 is provided at one end of the compression spring 52 away from the extension block 51. The adjusting ring 42 is vertically slidably sleeved on the outside of the support ring 41, and one end of the connecting rod 43 connected to the adjusting ring 42 is vertically slidably connected to the adjusting ring 42. A plurality of inner gear teeth are coaxially provided on the upper end of the inner surface of the adjusting ring 42, and a plurality of outer gear teeth meshing with the inner gear teeth are provided on the end surface of the locking portion 53 close to the adjusting ring 42. A guide rod is slidably provided between the extension block 51 and the locking portion 53, and the guide rod is coaxially arranged in the compression spring 52.

[0046] Since the guide rod is slidably disposed between the extension block 51 and the locking portion 53, when the compression spring 52 is extended or retracted, the guide rod is also extended or retracted, and the guide rod does not interfere with the extension or retraction of the compression spring 52. The guide rod serves as a guide for the extension or retraction of the guide rod, and the locking mechanism 5 as a whole has rigidity when subjected to a force in the horizontal radial direction of the guide rod, thereby ensuring the stability of the operation of the locking mechanism 5.

[0047] Sliding the adjusting ring 42 upward causes the inner gear teeth on the adjusting ring 42 to abut against the outer gear teeth on the locking portion 53 in the vertical direction. The locking portion 53 is subjected to the abutting force and then abuts against the compression spring 52, causing the locking portion 53 to retract inward until the force that causes the inner gear teeth to abut against the outer gear teeth in the vertical direction disappears. At this time, the compression spring 52 rebounds and causes the outer gear teeth on the locking portion 53 to abut against the inner gear teeth on the adjusting ring 42 in the horizontal direction. The inner gear teeth and the outer gear teeth mesh with each other and abut against each other, thereby locking the circumferential rotation of the adjusting ring 42.

[0048] In order to facilitate the outer gear teeth on the locking block to engage the inner gear teeth on the adjusting ring 42, as a further improvement, the lower end of the outer gear teeth is chamfered.

[0049] In order to limit the rotation of the adjustment ring 42 , as a further improvement, two positioning blocks 411 are provided on the inner surface of the support ring 41 , and a limiting block 11 is provided on the upper surface of the cylinder 1 , and the limiting block 11 is arranged between the two positioning blocks 411 .

[0050] The working principle of the utility model is as follows: when using the device to heat and keep the laparoscope warm, first rotate the adjusting ring 42 in the direction of loosening the rubber sealing strip 2 until the positioning block 411 abuts against the limit block 11 to obtain the maximum aperture of the fixing hole 21 to prepare for inserting the laparoscope, then insert the laparoscope into the barrel 1 through the fixing hole 21 and the entrance of the barrel 1 in turn, then rotate the adjusting ring 42 in the direction of tightening the rubber sealing strip 2 to tighten the fixing hole 21 until the fixing hole 21 abuts against the fixing laparoscope tube, and finally slide the adjusting ring 42 upward so that the adjusting ring 42 is engaged in the locking mechanism 5 to achieve the locking of the adjusting ring 42.

[0051] Example 2

[0052] Reference Figure 2 As shown, in order to achieve better fixing and shielding effects, this embodiment proposes improvements based on embodiment 1, and the rubber sealing strip 2 includes a receiving strip 22 arranged close to the positioning pin 3 and a clamping strip 23 arranged away from the positioning pin 3, the receiving strip 22 is provided with a clamping interface 221 for clamping the clamping strip 23, the positioning pin 3 includes an upper pin 32 and a lower pin 31 arranged at intervals above and below, the lower pin 31 hinges the receiving strip 22 to the upper surface of the cylinder 1, and the upper pin 32 hinges the receiving strip 22 to the upper surface of the cylinder 1 through the fixing strip 33.

[0053] If a single rubber sealing strip 2 is used, when the rubber sealing strip 2 is tightened and fixed to the laparoscope tube, the end of the rubber sealing strip 2 away from the positioning pin 3 will abut against the outer side surface of the end of the rubber sealing strip 2 close to the positioning pin 3, so that a gap is left between the end of the rubber sealing strip 2 away from the positioning pin 3 and the laparoscope tube, which will cause the fixing effect of the rubber sealing strip 2 on the laparoscope tube and the sealing effect on the entrance of the cylinder body 1 to be weakened. Therefore, by setting the rubber sealing strip 2 as a receiving strip 22 and a snap-in strip 23, when the rubber sealing strip 2 is tightened and fixed to the laparoscope tube, the snap-in strip 23 will be snapped into the snap interface 221 of the receiving strip 22, thereby minimizing the gap between the snap-in strip 23 and the laparoscope tube.

[0054] In order to prevent the positioning pin 3 from interfering with the clamping connection of the clamping strip 23 in the clamping interface 221, the positioning pin 3 is arranged at an upper interval to be an upper pin 32 and a lower pin 31. The lower pin 31 hinges the lower half of the accommodation strip 22 formed by the clamping interface 221 to the cylinder 1, and the upper pin 32 hinges the upper half of the accommodation strip 22 formed by the clamping interface 221 to the cylinder 1 through the fixing strip 33.

[0055] In order to further improve the shielding effect of the rubber sealing strip 2 on the inlet, as a further improvement, the rubber sealing strip 2 is provided with a shielding portion that completely shields the gap between the inlet on the upper surface of the barrel 1 and the laparoscope tube when the laparoscope tube is contracted and fixed.

[0056] During the tightening process of the rubber sealing strip 2, the axis of the fixing hole 21 is constantly moving in the direction close to the positioning pin 3. If the thickness of the rubber sealing strip 2 is not large enough, during the tightening process of the rubber sealing strip 2, a gap may be formed between the outer side surface of the rubber sealing strip 2 and the entrance of the cylinder 1. Therefore, a shielding portion is provided on the rubber sealing strip 2 to ensure the sealing performance of the rubber sealing strip 2 to the entrance of the cylinder 1.

[0057] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
