[0002] A laparoscope is a medical device used for minimally invasive surgery within the abdominal cavity. It is inserted into the abdominal cavity through a small incision made in the abdomen. It is equipped with a camera that transmits images to a monitor, allowing doctors to perform precise operations under visual conditions. Compared with traditional open surgery, it has the advantages of less trauma and faster recovery.
[0003] However, there are many technical difficulties in the clinical application of laparoscopic probes: coupling fluid needs to be applied before surgery to improve imaging quality, and the probe needs to be removed and wiped when blurred. The operation procedure is cumbersome and needs to be repeated, which significantly prolongs the surgical preparation time; during surgery, the probe is prone to fogging due to temperature difference after entering the abdominal cavity, and blood and exudates during the operation will contaminate the lens surface and affect the surgical field of view.
[0004] In all these cases, the probe needs to be removed from the abdominal cavity for treatment, which not only delays the surgical process and increases the risk of infection, but is also particularly disadvantageous when dealing with emergency situations such as active bleeding. In addition, repeated cleaning and heating treatments will accelerate the wear of the probe, reduce the service life of medical devices, and cause additional consumption of medical resources.

[0025] Example 1
[0026] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, and provides a laparoscope with a self-wiping objective lens surface, comprising a laparoscope body 1, and a cleaning unit 2 arranged on the outer wall of the outer mirror tube of the laparoscope body 1;
[0027] The cleaning unit 2 includes a first guide rail 21 and a second guide rail 22 arranged on the outer wall of its outer mirror tube, a first slider 23 arranged on the surface of the first guide rail 21, a second slider 24 arranged on the surface of the second guide rail 22, two limit blocks 25 arranged around the objective lens of the laparoscope body 1, and a wiper 26 arranged around the laparoscope body 1.
[0028] Furthermore, the first guide rail 21 includes first guide grooves 211 disposed on both sides thereof, and a spring groove 212 disposed on the upper surface of the first guide rail 21;
[0029] The second guide rail 22 includes second guide grooves 221 disposed on both sides thereof.
[0030] Furthermore, the first slider 23 includes a first dovetail groove 231 disposed at the bottom thereof, a spring rod 232 disposed at the end surface of the first slider 23, a spring 233 disposed on the outer wall of the spring rod 232, a first cylinder 234 disposed on the outer wall of the first slider 23, and a first wire groove 235 disposed on the outer wall of the first cylinder 234;
[0031] The second slider 24 includes a second dovetail groove 241 disposed at the bottom thereof, a second cylinder 242 disposed on the outer wall of the second slider 24 , a second wire groove 243 disposed on the outer wall of the second cylinder 242 , and a push block 244 disposed on one side of the second cylinder 242 .
[0032] Furthermore, the limiting block 25 includes a third wire groove 251 arranged on a side wall thereof.
[0033] Furthermore, the wiping member 26 includes traction lines 261 and a cleaning cloth 262 disposed between the traction lines 261 .
[0034] It should be noted that the laparoscope body 1 is a prior art, which is a rigid endoscope specially used for intra-abdominal inspection and surgery. It is inserted into the abdominal cavity to observe and operate the internal organs by making a small incision in the abdomen. Those skilled in the art should understand its principle and operation process, and will not be described in detail in this embodiment.
[0035] Preferably, there is a slender outer tube on the laparoscope body 1, and an objective lens is installed at the end of the outer tube. The first guide rail 21 and the second guide rail 22 are respectively fixed on the outer wall of the outer tube, symmetrically distributed and extending along the axial direction of the outer tube. The first guide rail 21 and the second guide rail 22 are located at one end close to the eyepiece and do not enter the abdominal cavity during surgery.
[0036] The first guide rail 21 and the second guide rail 22 have similar structures. Specifically, the first guide rail 21 has symmetrically distributed triangular first guide grooves 211 on both sides. The first guide grooves 211 extend along the axial direction of the first guide rail 21, and the two ends do not penetrate the two end surfaces of the first guide rail 21, so the cross section is dovetail-shaped. The first slider 23 has a first dovetail groove 231 at the bottom, and the first dovetail groove 231 completely penetrates the first slider 23. The first guide rail 21 and the first dovetail groove 231 cooperate with each other, so that the first slider 23 can move along the extension direction of the first dovetail groove 231. Since the first dovetail groove 231 does not penetrate the two ends, the travel of the first slider 23 during the movement is limited, and it cannot be separated from the first guide rail 21.
[0037] A spring groove 212 is also provided on the upper surface of the first guide rail 21. The spring groove 212 extends axially along the first guide rail 21, and both ends do not pass through the first guide rail 21, and can be used to accommodate a spring rod 232. The spring rod 232 is fixed at the end surface of the first slider 23 facing the objective lens, and completely passes through the end surface of the first guide rail 21 facing the objective lens. Therefore, during the movement of the first slider 23, the spring rod 232 also expands and contracts within the end surface of the first guide rail 21 facing the objective lens.
[0038] In addition, a spring 233 is sleeved on the spring rod 232, and the two ends of the spring 233 are respectively fixed to the end surface of the first slider 23 facing the objective lens and the end surface of the spring groove 212 facing the objective lens. Therefore, the entire first slider 23 can be pushed toward the side facing the eyepiece. Since the spring 233 is long, the spring rod 232 is needed to stabilize the compression direction of the spring 233 to prevent it from popping out.
[0039] Preferably, the two side walls of the second guide rail 22 are provided with symmetrically distributed second guide grooves 221 whose structure and size are consistent with the first guide groove 211 and can cooperate with the second dovetail groove 241 provided on the surface of the second slider 24, so that the second slider 24 can move axially along the second guide rail 22.
[0040] Preferably, a first cylinder 234 is fixed on the surface of the first slider 23 along the radial direction of the outer mirror tube, and a first wire groove 235 is opened at the column foot of the first cylinder 234. Similarly, a second cylinder 242 is fixed on the surface of the second slider 24 along the radial direction of the outer mirror tube, and a second wire groove 243 is opened at the column foot of the second cylinder 242.
[0041] The first wire groove 235 and the second wire groove 243 are annular in shape, and have the same groove width and groove depth.
[0042] Preferably, a push block 244 is fixed on the outer surface of the second sliding block 24 adjacent to the second cylinder 242 for easy operation by medical staff.
[0043] Preferably, on both sides of the objective lens, two symmetrically distributed limit blocks 25 are fixed on the outer wall of the outer mirror tube end, the limit blocks 25 are waist-shaped, and a third wire groove 251 is opened on the side wall of each limit block 25, and the groove width and groove depth are consistent with the first wire groove 235 and the second wire groove 243.
[0044] Preferably, the type of traction line 261 can be a line made of plant fiber or an artificially synthesized organic polymer line, which can reduce the loss of each line slot during movement and avoid the contamination of the abdominal cavity by fine particles caused by friction. The traction line 261 is connected at both ends, and a cleaning cloth 262 is fixed on two adjacent line segments. The cleaning cloth 262 can be a gauze sponge or the like.
[0045] Preferably, the end-to-end traction wire 261 needs to be inserted into the first wire groove 235, and then the two wires pass through and insert into the third wire groove 251 respectively, and finally insert into the second wire groove 243. The cleaning cloth 262 needs to be on the same side of the first guide rail 21 and adjacent to the objective lens of the laparoscope.
[0046] When in use, the cleaning cloth 262 needs to be soaked before the operation, and then the cleaning cloth 262 is set in the order of the first wire groove 235, the third wire groove 251 and the second wire groove 243, and the cleaning cloth 262 is ensured to be placed adjacent to the objective lens. At this time, the traction line 261 needs to be in a tensioned state, that is, when it is inserted into the first wire groove 235 and passes through the third wire groove 251, the first slider 23 is pulled to overcome the resistance of the spring 233 until it is inserted into the second wire groove 243. At this time, the state should be that the spring 233 cannot be completely reset, and the second slider 24 is close to the second guide rail 22 toward one end of the objective lens.
[0047] When the objective lens surface needs to be cleaned, the medical staff needs to push the push block 244 toward the eyepiece so that the traction line 261 pulls the first slider 23 toward the eyepiece. At this time, the cleaning cloth 262 passes over and wipes the objective lens surface, and after cleaning the lens contaminants, the coupling liquid is applied to the mirror surface.
[0048] After the push block 244 is released, under the action of the spring 233, the traction line 261 pulls the second slider 24 in the reverse direction to the travel limit, so as to facilitate the next wiping and cleaning.
[0049] In summary, this design allows the laparoscope to wipe the objective lens surface through the wiper during surgery, effectively avoiding the lens from fogging due to temperature difference during surgery and being easily contaminated by blood and exudates. In addition, the wiper can be soaked with coupling liquid and the wiping action is completed, thereby constantly improving the imaging quality during surgery, avoiding the risk of infection and bleeding caused by frequent removal of the laparoscope from the abdominal cavity, and improving surgical efficiency while simplifying the operation.
[0050] It is important to note that the above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
