Technical Field

[0001] The present application relates to the technical field of appendix fecal stone sampling equipment, and in particular to a fecal stone sampling net basket and a method for using the same. Background Art

[0002] Appendectomy is an emerging treatment method that removes stones from the appendix through endoscopic retrograde appendectomy (ERAT), thus avoiding traditional appendectomy. ERAT technology uses a colonoscope to reach the appendix opening, then inserts a guidewire and catheter into the appendix cavity to perform flushing, stone removal, catheter drainage, etc. to treat appendicitis. This method is suitable for acute edematous, purulent appendicitis, especially those caused by appendiceal fecal stones.

[0003] After appendectomy, the preservation and analysis of fecal stones is an important step in pathological research. By analyzing fecal stones, doctors can better analyze the pathological changes of the appendix and find out the causes of fecal stone formation. However, after the current appendectomy stone removal instruments enter the appendix, they usually take the fecal stones into the intestines and then discharge them. They do not have a structure that can take and retain fecal stones, making it difficult to take out complete fecal stones for preservation and analysis.

[0004] Therefore, the prior art still needs to be improved and developed, and lacks a kind of appendix fecal stone sampling equipment that can collect and retain fecal stone. Summary of the invention

[0034] The invention is further described below by describing embodiments in conjunction with the accompanying drawings.

[0035] This embodiment provides a fecal stone removal basket and a method of using the same. Figures 1 to 3 As shown in , in order to solve the above technical problems, the technical solution adopted by the present invention is as follows: comprising: a stone basket 100 and a sleeve 200, the stone basket 100 is used to sleeve fecal stones, and the sleeve 200 is used to support the stone basket 100. In actual use, the stone basket 100 is sent into the appendix cavity of the patient for use.

[0036] The stone retrieval basket 100 includes: a plurality of basket wires 110, the plurality of basket wires 110 are elastic, each basket wire 110 is in a straight line, one end of each basket wire 110 is connected to form a distal end 120, and the other end passes through a sleeve 200 to form a driving portion, and a stone storage area is formed between all basket wires 110. Specifically, when all basket wires 110 are in a straight line, the outer diameter of the stone retrieval basket 100 is the smallest, and at this time, it can be conveniently delivered into the appendix cavity of the patient.

[0037] The stone basket 100 has a picking state and a clamping state through the movement of the driving part: in the picking state, the driving parts of some basket wires 110 move along the casing 200 away from the distal end 120, and the driving parts of the remaining basket wires 110 are stationary relative to the casing 200, and the remaining basket wires 110 are driven to bend to enlarge the stone storage area;

[0038] In the clamped state, a plurality of bent basket wires 110 drive the driving portions of the remaining basket wires 110 to move toward the distal end 120, and each basket wire 110 is driven to move closer to each other, thereby reducing the stone storage area.

[0039] Specifically, by controlling the relative movement of different driving parts, several basket wires 110 can be bent, and the state in which the stone storage area becomes larger can be called a picking state; conversely, several basket wires 110 are straightened, and the state in which the stone storage area is reduced can be called a clamping state. When the stone retrieval basket 100 is in the picking state, it can be used to pick up fecal stones in the appendix cavity of the patient. When the stone retrieval basket 100 is in the clamping state, the fecal stones can be retained in the stone storage area. At this time, the stone retrieval basket 100 can be taken out of the appendix to obtain a complete fecal stone. Among them, the elasticity of the basket wire 110 can be selected according to actual conditions, as long as it satisfies the medical staff to bend the basket wire 110 by moving the driving part without the help of external force, and can automatically change from the picking state to the clamping state without the help of external force.

[0040] In one embodiment, Figure 1 , Figure 2 , Figure 3 As shown in , the basket wire 110 includes: a plurality of soft wires 111 and a plurality of elastic wires 112, the soft wires 111 are not elastic, and the elastic wires 112 are elastic. Preferably, the material of the elastic wires 112 is the same as the common spring material, and the soft wires 111 are ropes, preferably diamond wires.

[0041] In the picking state, the driving parts of the plurality of soft wires 111 move along the sleeve 200 in a direction away from the distal end 120, and the driving part of the elastic wire 112 is stationary relative to the sleeve 200, and the elastic wire 112 is driven to bend to enlarge the stone storage area;

[0042] In the clamped state, a plurality of curved elastic wires 112 drive the driving portion of the soft wire 111 to move toward the distal end 120, and each basket wire 110 is driven to move closer to each other, thereby reducing the stone storage area.

[0043] In one embodiment, Figure 2 , Figure 3 As shown in , there are five elastic wires 112, and in the picking state, the angle between the projections of every two adjacent elastic wires 112 on the plane perpendicular to the distal end 120 is 45°;

[0044] The soft wire 111 is located outside the five elastic wires 112 . There are two soft wires 111 , and the angle between the projections of the soft wire 111 and the adjacent elastic wire 112 on the plane perpendicular to the distal end 120 is 30°.

[0045] Specifically, through the above-mentioned angle, the five elastic wires 112 can form a spoon shape with an opening of 180°, which is convenient for picking up fecal stones, and the soft wire 111 is located outside the five elastic wires 112, and the angle between the projections of the two soft wires 111 on the plane perpendicular to the distal end 120 is 120°. The opening angle is large, which is convenient for picking up fecal stones.

[0046] In one embodiment, Figure 1 As shown in , the fecal stone removal net basket also includes: a first driving bracelet 310, the first driving bracelet 310 is connected to the driving part of the soft wire 111, and the first driving bracelet 310 is used to be fixed on the finger;

[0047] The second driving bracelet 320 is connected to the driving part of the elastic wire 112, and the second driving bracelet 320 is used to be fixed on the finger.

[0048] In actual use, different fingers can be fixed on the first driving bracelet 310 and the second driving bracelet 320 respectively to control the movement of the driving part of the soft wire 111 and the driving part of the elastic wire 112 respectively.

[0049] In one embodiment, Figure 1 As shown in , the fecal stone removal basket also includes: a handle portion 400, the handle portion 400 is connected to the sleeve 200, and the first driving bracelet 310 and the second driving bracelet 320 are respectively slidably arranged on the handle portion 400 toward the stone removal basket 100.

[0050] Specifically, by limiting the sliding direction of the first driving bracelet 310 and the second driving bracelet 320, the first driving bracelet 310 and the second driving bracelet 320 can be prevented from moving in a direction perpendicular to the distal end 120, thereby facilitating the control of the movement of the driving part of the soft wire 111 and the driving part of the elastic wire 112.

[0051] In one embodiment, Figure 1As shown in , the fecal stone removal basket also includes: a fixed bracelet 410, which is arranged at the end of the handle portion 400 away from the stone removal basket 100, and the fixed bracelet 410 is used to be fixed on the finger.

[0052] During actual use, different fingers can be fixed on the first driving bracelet 310, the second driving bracelet 320 and the fixed bracelet 410 respectively. The fixed bracelet 410 can better control the movement of the driving parts of the soft wire 111 and the elastic wire 112 relative to the sleeve 200.

[0053] In one embodiment, Figure 1 As shown in , the second driving bracelet 320 is arranged between the first driving bracelet 310 and the stone basket 100. When the first driving bracelet 310 contacts the second driving bracelet 320, the stone basket 100 is in a picking state.

[0054] In actual use, the first driving bracelet 310 can be driven toward the direction of the fixed bracelet 410. At this time, if the first driving bracelet 310 contacts the second driving bracelet 320, the stone basket 100 can be placed in a picking state. Specifically, the entire stone basket 100 can be moved relative to the sleeve 200 without changing the state by simultaneously controlling the first driving bracelet 310 and the second driving bracelet 320 to move toward or away from the fixed bracelet 410. Through this operation, the stone basket 100 can be located or not located in the sleeve 200, or extended out of the sleeve 200. When the stone basket 100 is located in the sleeve 200, it is convenient to send the stone basket 100 into the appendix cavity of the patient; on the contrary, when the length of the sleeve 200 is not enough, the stone basket 100 can be extended out of the sleeve 200 to pick up fecal stones away from the sleeve 200.

[0055] In one embodiment, Figure 1 , Figure 2 , Figure 3 As shown in , the fecal stone removal basket also includes: a limiting portion 500 , which is arranged on the distal end 120 , and the outer diameter of the limiting portion 500 is greater than the inner diameter of the sleeve 200 .

[0056] Preferably, in actual use, the first driving bracelet 310 and the second driving bracelet 320 can be simultaneously controlled to move toward or away from the fixed bracelet 410 so that the entire stone removal basket 100 can move relative to the sleeve 200 without changing its state. Due to the presence of the limiting portion 500, the stone removal basket 100 can be prevented from being completely embedded in the sleeve 200.

[0058] All driving parts are released, and a plurality of bent basket wires 110 drive the driving parts of the remaining basket wires 110 to move toward the distal end 120, and each basket wire 110 is driven to approach each other so that the stone storage area is reduced to clamp the fecal stone.

[0059] In summary, the present application relates to the technical field of appendix fecal stone sampling equipment, and discloses a fecal stone extraction net basket and a method of using the same, which includes a stone extraction basket and a sleeve, wherein the stone extraction basket includes a plurality of basket wires, the plurality of basket wires are elastic, each basket wire is in a straight line, one end of each basket wire is connected to each other to form a distal end, and the other end passes through the sleeve to form a driving part, and a stone storage area is formed between all the basket wires; wherein the stone extraction basket has a picking state that enlarges the stone storage area and a clamping state that shrinks the stone storage area through the movement of the driving part. The present invention arranges a stone extraction basket, and after the stone extraction basket is sent into the appendix, the movement of the driving parts of the plurality of basket wires can be controlled to control the stone extraction basket to be in a picking state that enlarges the stone storage area or a clamping state that shrinks the stone storage area, and when the stone extraction basket is in a picking state, it can be used to pick up fecal stones, and when the stone extraction basket is in a clamping state, the fecal stones can be retained in the stone storage area, and at this time, the stone extraction basket can be taken out of the appendix to obtain a complete fecal stone.
