[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0030] Reference Figure 1 and Figure 2 The utility model discloses an endoscopic sampling device, comprising a sleeve seat 100, a core wire 400 and two clamp arms 300. One end of the sleeve seat 100 is used to be sleeved on the head of an endoscope 200, and the end surface of the other end of the sleeve seat 100 is provided with a core wire window 120, an objective lens window 130 and two support plates 140; the middle parts of the two clamp arms 300 are respectively hinged on the two support plates 140, and one end of the two clamp arms 300 is provided with a clamp part 310 for clamping diseased tissue; one end of the core wire 400 can be sequentially passed through the endoscope channel and the core wire window 120 of the endoscope 200, and the end of one end of the core wire 400 is connected to the other ends of the two clamp arms 300, and the core wire 400 can drive the two clamp parts 310 to open and close.
[0031] The two support plates 140 serve to support the two clamp arms 300 , which can rotate on the two support plates 140 respectively. When the core wire 400 is pushed and pulled, the core wire 400 drives the two clamp arms 300 to rotate on the two support plates 140 respectively, thereby opening and closing the two clamp parts 310 .
[0032] When a biopsy is required, the sampling method is as follows: one end of the sleeve seat 100 is sleeved on the head of the endoscope 200, and after one end of the core wire 400 passes through the endoscope channel and the core wire window 120 of the endoscope 200 in sequence, the end of one end of the core wire 400 is connected to the other end of the two clamp arms 300, and the objective lens and the light-emitting component of the endoscope 200 are both opposite to the objective lens window 130. Then the endoscope 200 is inserted into the human body and transported to the lesion. The head of the endoscope 200 carries the sampling device to enter the lesion, and then the two clamps 310 are driven to open by the core wire 400. When the diseased tissue is between the two clamps 310, the two clamps 310 are driven to close by the core wire 400, so that the two clamps 310 clamp the diseased tissue and remove the diseased tissue from the human body. Finally, the endoscope 200 is pulled out of the human body, and the head of the endoscope 200 carries the sampling device and the diseased tissue and moves outside the human body to finally obtain the diseased tissue.
[0033] When one end of the sleeve seat 100 is sleeved on the head of the endoscope 200, the objective lens and the light-emitting element of the endoscope 200 are directly opposite to the objective lens window 130, so the endoscope 200 can provide a field of view for medical staff, and through the endoscope 200, the situation in the human body can be observed, so as to know the situation of the lesion and the diseased tissue and move the sampling device, and then operate the sampling device to remove the diseased tissue. It can be understood that the endoscope 200 is a common device on the market. The two clamp arms 300 have the same structure.
[0034] The sampling device is installed at the head of the endoscope 200. During operation, the endoscope 200 and the sampling device are used synchronously, without the need to first insert the endoscope 200 into the human body and then insert the sampling device into the human body through a mechanism such as a spring sleeve. During biopsy, the sampling device of the present application reduces the number of operating steps and the number of mechanisms inserted into the human body, thereby reducing the discomfort of the patient. Compared with biopsy forceps, the sampling device has a simpler structure, is easier to manufacture, has a low cost, and is easy to operate.
[0035] See also Figure 3 and Figure 4 The other ends of the two clamp arms 300 are each provided with a limiting slide groove 320, and the length direction of the limiting slide groove 320 is the same as the length direction of the other end of the clamp arm 300. The end of one end of the core wire 400 is provided with two sliding shafts 410, and the two sliding shafts 410 extend into the two limiting slide grooves 320 respectively. The diameter of the sliding shaft 410 and the width of the limiting slide groove 320 cooperate with each other, so that the sliding shaft 410 can slide in the limiting slide groove 320 along the length of the limiting slide groove 320.
[0036] After the two sliding shafts 410 of the core wire 400 extend into the two limiting slide grooves 320, the limiting slide grooves 320 play the role of limiting the sliding shafts 410. When the core wire 400 is pushed and pulled, the core wire 400 drives the two sliding shafts 410 to move, and the sliding shafts 410 push the side walls of the limiting slide grooves 320, that is, push the clamp arms 300, thereby driving the two clamp arms 300 to rotate on the two support plates 140 respectively.
[0037] See also Figure 2 and Figure 3 In some of the embodiments, an ear plate 420 is provided at the end of one end of the core wire 400, and two sliding shafts 410 are respectively arranged on two sides of the ear plate 420, and the two sliding shafts 410 are coaxially arranged. The two sliding shafts 410 can act on the two clamp arms 300 synchronously. Since the two clamp arms 300 have the same structure, the two clamp parts 310 have the same structure, and the two clamp arms 300 are arranged opposite to each other, the core wire 400 can synchronously drive the two clamp arms 300 to move, thereby making the two clamp parts 310 move symmetrically.
[0038] It is conceivable that the symmetry plane of the two support plates 140 and the symmetry plane of the two clamp parts 310 are the same symmetry plane.
[0039] See also Figure 2 and Figure 4 In some embodiments, the middle of the two clamp arms 300 is provided with a shaft hole 330, and the two support plates 140 are provided with a shaft 500, and the two shafts 500 are respectively passed through the two shaft holes 330, so that the clamp arms 300 can rotate on the support plates 140. The two clamp arms 300 are respectively hinged on the two support plates 140 through the two shafts 500, and the two clamp arms 300 are respectively rotated on the two support plates 140.
[0040] In some embodiments, the core wire window 120 is disposed between the two support plates 140, the two rotating shafts 500 are disposed on both sides of the plane formed by the two support plates 140, and the two clamp arms 300 are disposed on the two rotating shafts 500, so that the structure of the sampling device is relatively compact. More specifically, the length direction of the central axis of the rotating shaft hole 330 is parallel to the depth direction of the limiting slide groove 320, the notches of the two limiting slide grooves 320 are both oriented toward the plane formed by the two support plates 140, and the notches of the two limiting slide grooves 320 are oriented in opposite directions.
[0041] The clamp arm 300 is plate-shaped, and the clamp portion 310 is a (left-right) symmetrical structure. The clamp portion 310 has a symmetrical plane. The clamp portion 310 is connected to the clamp arm 300 in an area deviated from the symmetrical plane (to the left or right). When the two clamp portions 310 are put together, the two clamp arms 300 can avoid interference with each other.
[0042] In some of the embodiments, the two jaws 310 are both spoon-shaped, and the two jaws 310 can form a sealed cavity for storing diseased tissue. The sealed cavity seals and wraps the diseased tissue to prevent the diseased tissue from escaping from the sampling device and falling into other areas of the human body.
[0043] It can be imagined that the clamp part 310 includes a front end, a middle section and a rear end connected in sequence, the front end and the rear end are both quarter structures of the spherical shell, the middle section is half the side wall of the circular tube, the front end, the middle section and the rear end together form a half-groove cavity, and when the two clamp parts 310 are closed, the two half-groove cavities form a sealed cavity.
[0044] See also Figure 1 and Figure 2 In some embodiments, the sleeve seat 100 includes a tubular portion and a supporting portion, one end of the tubular portion is used to be sleeved on the endoscope 200, the supporting portion is arranged on the other end of the tubular portion, and the supporting portion covers a partial area of the port at the other end of the tubular portion, and the remaining area of the port at the other end of the tubular portion is the objective lens window 130, and the core wire window 120 and two support plates 140 are all arranged on the supporting portion.
[0045] See also Figure 1 , Figure 2 and Figure 5 In some of the embodiments, one end of the sleeve holder 100 is provided with a plurality of connecting parts 110 for connecting to the outer wall of the endoscope 200. The connecting parts 110 make the connection between the sleeve holder 100 and the endoscope 200 more secure, thereby preventing the sleeve holder 100 from accidentally falling off the head of the endoscope 200, and further preventing the sampling device from accidentally falling into the human body.
[0046] See also Figure 6 In some of the embodiments, a hook portion 111 is provided at one end of the plurality of connecting portions 110 away from the sleeve seat 100 , and the hook portion 111 is used to hook onto the outer wall of the endoscope 200 .
[0047] It is conceivable that an annular groove is provided on the outer wall of the endoscope 200 , and the hook portion 111 can be firmly hooked on the inner groove wall of the annular groove to ensure the reliability of the connection between the connecting portion 110 and the endoscope 200 .
[0048] The hook portion 111 protrudes from the inner wall of the connecting portion 110 , the outer side surface of the hook portion 111 and the outer side surface of the connecting portion 110 are smoothly transitioned, and the inner side surface of the hook portion 111 and the inner side surface of the connecting portion 110 form a right angle.
[0049] See also Figure 2 , Figure 5 and Figure 6 In some embodiments, a plurality of partition grooves 150 are formed on the side wall of one end of the sleeve seat 100, and the length direction of all the partition grooves 150 is the same as the length direction of the sleeve seat 100. A connecting portion 110 is formed between two adjacent partition grooves 150. The partition grooves 150 can be directly cut out of the sleeve seat 100, and the connecting portion 110 can be processed. The processing method is simple. Since the connecting portion 110 is a thin plate structure, the connecting portion 110 can undergo a certain degree of elastic deformation, which makes it easier to bend all the connecting portions 110 toward the outside of the sleeve seat 100, and finally to put one end of the sleeve seat 100 on the head of the endoscope 200.
[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
