[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides an adjustable transverse colonic loop stoma support rod, including an outer core rod 1, an inner core rod 2 and an adjustment knob 3. The outer core rod 1 is provided with through holes distributed along the length direction. The size of the through holes matches the size of the inner core rod 2. The adjustment knob 3 can be rotatably mounted on the outer core rod 1 and extends into the through holes.

[0032] The outer surface of the inner core rod 2 is provided with a first rack 201 and a second rack 202 distributed along the length direction. The first rack 201 and the second rack 202 form a track that cooperates with the adjustment knob 3. One end of the inner core rod 2 is located in the through hole, and the adjustment knob 3 is located in the track of the inner core rod 2, so that the length of the transverse colon loop stoma support rod can be adjusted by adjusting the adjustment knob 3.

[0033] Adjustment knob 3 is an adjustment knob with a self-locking function. After the overall length of the adjustable transverse colon loop stoma support rod is set by rotation, adjustment knob 3 can be locked to fix the length.

[0034] The adjustable transverse colostomy support rod provided in this solution, by setting an outer core rod and an inner core rod, and by rotating the adjustment knob, drives the inner core rod to extend and retract within the outer core rod through the rack on the inner core rod, so as to adjust the length of the transverse colostomy support rod. The adjustment operation is simple, simplifies the surgical procedure, and increases safety.

[0035] Preferably, the inner core rod 2, outer core rod 1, and adjusting knob 3 are all made of plastic, which makes the material safer. At the same time, the selection of plastic materials needs to consider non-toxicity and harmlessness, anticoagulant properties (instruments that come into contact with blood must avoid hemolysis or blood cell reduction, and prevent protein denaturation), sterilization adaptability, low metal residue (strict control of lead, cadmium, copper, and other metal ion content (complying with standards such as GB / T16288-2008)), additive safety (prohibition of harmful plasticizers (such as DEHP in PVC), ensuring no toxic substances are released during long-term use), and mechanical properties (must meet wear resistance and deformation resistance requirements).

[0036] Preferably, the end edge of the inner core rod 2 is a rounded bend 4, and the end edge of the outer core rod 1 is a rounded bend 4, to reduce the possibility of skin damage during placement.

[0037] like Figure 2 As shown, the adjustment knob 3 has teeth 301 that cooperate with the first rack 201 and the second rack 202. When the adjustment knob 3 is rotated, the transmission between the teeth 301 and the first rack 201 and the second rack 202 drives the first rack 201 and the second rack 202 to move, thereby realizing the movement of the inner core rod 2.

[0038] The adjusting knob 3 is rotatably connected to the outer mandrel 1 via the parallel thread 302. The thread profile of the parallel thread is symmetrically distributed on both sides, the thread pitch of each turn is equal, and there is no taper in the axial direction. In this design, the adjusting knob 3 is fixed in position but can be rotated.

[0039] Preferably, the inner core rod 2 is further provided with a first blocking block and a second blocking block at both ends, and the first blocking block and the second blocking block are respectively fixed at both ends of the track. By blocking the inner core rod 2 from falling out of the outer core rod 1 by the first blocking block and the second blocking block, the inner core rod 2 is prevented from falling out of the outer core rod 1, and the adjusting knob 3 is prevented from disengaging from the inner core rod 2.

[0040] In this embodiment, the maximum length of the adjustable transverse colostomy support rod is 15cm, and the adjustment knob 3 is located in the middle of the adjustable transverse colostomy support rod; both the inner core rod 2 and the outer core rod 1 are cylindrical structures. The inner diameter of the adjustable transverse colostomy support rod is 10mm.

[0041] Rotate adjustment knob 3 clockwise 180° to advance the inner core rod by 0.5cm; rotate adjustment knob 3 counterclockwise 180° to retract the inner core rod by 0.5cm.

[0042] The principle behind the function of "rotating the middle knob 180° to drive the inner core to move linearly by 0.5cm" is mainly achieved through the mechanical conversion of rotational motion to linear motion. The linear relationship between the knob's rotation angle and the inner core's displacement is designed to satisfy the transmission ratio of 180° rotation = 0.5cm displacement.

[0043] Preferably, backlash can be eliminated by adding a backlash-eliminating spring to improve motion accuracy.

[0044] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
