In one embodiment, a distal cap apparatus includes a mount having a strap and a buckle for adjusting a size of a loop formed at least partially by the strap about the distal end of the endoscope.

A method for manufacturing a stent delivery system is a method for manufacturing a stent delivery system that includes a balloon catheter including a balloon and a shaft supporting the balloon, and a stent disposed on the balloon and formed in a tubular shape, the balloon being joined to the shaft at an end portion in an extending direction of the shaft. The method includes a first diameter reduction step of compressing the stent inward in a radial direction of the stent to reduce diameters of the stent and the balloon in a state where the balloon is inserted into a tube of the stent, and then releasing the compression. In the first diameter reduction step, the stent is compressed to a first diameter, the first diameter being equal to or smaller than a diameter of a proximal-side joint portion where the balloon is fused to the shaft.

The holder for medical tools includes: a medical tool including a tool shaft; a holder main body internally formed with a tool mounting hole to insert the medical tool therein; and a tool supporting means supporting the medical tool inserted in the holder main body, wherein the tool supporting means includes a tool support guide member to guide movement of the tool shaft while supporting the tool shaft.

To provide a method for manufacturing a stent delivery system and a stent delivery system achieving reduction of the diameter of a balloon catheter to which a stent is crimped.SOLUTION: The method for manufacturing a stent delivery system 200 is a method for manufacturing a stent delivery system 100 which includes a balloon catheter 100 having a balloon 1 and a shaft 5 for supporting the balloon 1, and a stent 2 that is arranged on the balloon 1 and is cylindrically formed, with the end part of the balloon 1 in an extending direction of the shaft 5 joined to the shaft 5. The method includes a first diameter reduction process for compressing the stent 2 inwards in a radial direction of the stent 2, with the balloon 1 inserted into a cylinder of the stent 2, to reduce the diameters of the stent 2 and the balloon 1 and then releasing the compression. In the first diameter reduction process, the stent 2 is compressed to a first diameter, and the first diameter is equal to or smaller than the diameter of a base-end side joint portion 16 where the balloon 1 is fused to the shaft 2.SELECTED DRAWING: Figure 3

The utility model discloses a clamping device for scalpel calcination processing, and relates to the technical field of scalpel calcination processing. The device comprises a bottom plate, the top of the bottom plate is fixedly connected with a clamping box, and the top of the clamping box is provided with a box cover; a clamping assembly is arranged in an inner cavity of the clamping box and comprises supports, and the supports are connected to the two sides of the inner cavity of the clamping box in a sliding mode. A scalpel to be calcined can be effectively placed through the overhead plate at the top of the support, the inserting frame at the bottom of the box cover is inserted into the support, extrusion force is applied to the pressed block in the support, the connecting rod can be driven to rotate on the surface of the rotating shaft, and therefore the overhead plate moves upwards, and the scalpel can be calcined. Meanwhile, the position of the scalpel can be firmly fixed through the pressing plate in the inserting frame, and it is guaranteed that the two faces of the scalpel can be evenly heated in the calcining process.

To suppress damage to a terminal when a holder is released from a fully locked state to a provisionally locked state.SOLUTION: A connector with a holder includes a male housing 3 provided with a first male terminal 1 that protrudes into a holder accommodating portion 5, and a male front holder 4 that is inserted into the holder accommodating portion 5 and can be engaged with a base wall portion 6 of the male housing 3. The male front holder 4 includes a base portion 15, a rib main body portion 16 that protrudes from the base portion 15 toward the open end 5a of the holder accommodating portion 5, and a rib reinforcing portion 17 that protrudes from an upper surface 16a of the rib main body portion 16. An insertion hole 21 is formed in the rib main body portion 16 at a position adjacent to the rib reinforcing portion 17 and the base portion 15. A hook portion 22c provided at the tip of a removal jig 22 that moves the male front holder 4 relative to the male housing 3 is inserted into the insertion hole 21.SELECTED DRAWING: Figure 2

Disclosed are an ampoule-fixing holder for an intraosseous anesthetic solution injection device and an anesthetic solution injection device including the same. The ampoule-fixing holder includes a cylindrical holder body including an open portion formed at the rear end thereof to allow an ampoule containing an anesthetic solution to be inserted thereinto or removed therefrom, a head configured to enable mounting of an injection needle to the front end of the holder body, a rotary body disposed between the head and the holder body to withstand rotational force and an axial load, and a fixing member configured to firmly hold the ampoule inserted into the holder body to effectively transmit rotational force to the ampoule.

A polyp retrieval device, a filter (1) thereof, and a support (2) thereof. The filter (1) applied to the polyp retrieval device comprises a body (10), and a liquid injection hole (13) and a liquid filtration mechanism which are arranged on the body (10). The body (10) comprises an upper housing (11) and a lower housing (12) which are interlocked with each other. An accommodating cavity (100) for retrieving a polyp is formed between the upper housing (11) and the lower housing (12). The body (10) of the filter (1) adopts a structure in which the upper housing (11) and the lower housing (12) are hinged, so that when the filter (1) is inserted into the support (2), the upper housing (11) and the lower housing (12) are interlocked with each other to form the accommodating cavity (100), which can prevent the polyp from splashing out of the filter (1), thereby avoiding sample loss caused by the discharge of a living tissue sample out of the support (2), ensuring enough samples for a doctor to complete pathological analysis, reducing the probability of secondary biopsy, and thus sparing the patient from unnecessary pain and also saving medical resources. Additionally, manual collection of a polyp sample remaining on an inner wall of the support (2) is not required, thereby reducing the cleaning difficulty of the support (2).

The utility model discloses an anti-displacement urethral stent, and relates to the technical field of urethral stents, the anti-displacement urethral stent comprises a stent main body and a through hole, the middle part of the stent main body is provided with the through hole, and two sides of the stent main body are provided with auxiliary mechanisms. When the anti-displacement urethral stent is used, the input end and the output end are fixed to the two sides of the stent body through the auxiliary mechanism, and the input end and the output end are both conical, so that the front end of the stent is rounder and smoother through the input end, friction and damage to urethral tissue are reduced, and the anti-displacement urethral stent is more convenient to use. The urethral stent can more easily pass through a narrow or bent part of the urethra, so that the pain and discomfort of a patient can be relieved; and the output end is used for assisting the urine to be smoothly discharged, so that the urine is prevented from being accumulated between the stent and the urethral wall, and the effects of conveniently inserting the stent to reduce stimulation and assisting urination are achieved when the urethral stent is used.
