A distal cap apparatus for use with an endoscope, having a proximal end and a distal end and a longitudinal axis extending therebetween, includes a mount configured for mounting to the distal end of the endoscope, and a strap connected to the mount and configured for banding about the distal end of the endoscope when the distal end of the endoscope is received in the mount. The mount defines a strap slot configured to receive an end of the strap to configure the strap in the banded configuration. The strap may be elastic. The strap may be a continuous band. 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.

An embodiment relates to a holder for medical tools, to which an impactor, a reamer, etc. used in a surgical operation is mounted, and more specifically, to a holder for medical tools, which has a concise and simple structure, satisfies operational stability and durability, and is usable interchangeably. 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.

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.
