Description

Medical tool matched with endoscope forceps channel

Technical Field

The utility model relates to a medical tool matched with an endoscope channel, in particular to an outer wall structure of a catheter structure.

Background

The endoscope is a common medical instrument and enters the deep part of the body through a natural or artificial pore canal to achieve the purposes of examination and treatment. The endoscopes which are commonly used clinically include gastroscopes, colonoscopes, bronchoscopes, laryngoscopes, cystoscopes and the like. The endoscope is structurally provided with functions of illumination, image acquisition, gas injection, water injection and the like, and is generally provided with a hollow pipeline called a biopsy forceps channel or a forceps channel, wherein the length of the forceps channel is consistent with that of the endoscope, and the diameter of the forceps channel is unequal. If the standard diameter of the gastroscope clamping passage is 2.8mm, the diameter of the superfine gastroscope clamping passage is 2.0mm, the diameter of the enteroscope clamping passage is 3.2mm, and other treatment endoscopes with special functions can have slightly larger clamping passage diameters. As a conduit for an endoscope to communicate the body cavity with the exterior, the forceps channel is the only way for all endoscopic accessories to enter the body cavity. These accessories include biopsy forceps, foreign body forceps, spray catheters, endoscopic injection needles, baskets, needle knives, snare instruments, various endoscopic undercutters, thermal probes, thermal hemostats, laser fibers, argon knife catheters, microwave probes, metal clips, nylon cords, and the like.

Taking endoscope biopsy forceps and foreign body forceps as examples, the forceps heads of the endoscope biopsy forceps and the foreign body forceps are made of medical stainless steel and silicon rubber materials, the outer tube is made of medical stainless steel and PTFE materials, the pull cable is made of medical stainless steel materials, and the handle is made of ABS materials. The head is designed with various shapes, is suitable for grabbing various foreign matters and is convenient to use. For example, CN201310211659 discloses a pair of foreign body forceps, which comprises a handle, a slider, an outer tube, a pulling cable and a head functional end, wherein the handle is provided with a sliding groove, the slider is slidably mounted in the sliding groove, the pulling cable is sleeved in the outer tube, the slider is connected with the pulling cable, the far end of the pulling cable is connected with a net sleeve, the sleeved end of the outer tube and the pulling cable is provided with a positioning butt joint tube, and the endoscope foreign body forceps at the end part of the positioning butt joint tube sleeved in the outer tube is composed of a sleeve, an operating handle, a push-pull rod, a clamping. Similar patents include CN201710764449.9 an endoscopic foreign body forceps, CN201720762481 a throat foreign body forceps with a bendable front end, CN 200520077031 improved endoscopic snare and endoscopic surgical instruments of the prior application of the present utility model, etc.

Because the total length of the endoscope is long, even 160 cm, and the diameter of the outer tube is slightly smaller than that of the forceps channel, when a surgical instrument (the length of which is longer than the total length of the endoscope) matched with the endoscope needs to be quickly inserted into the forceps channel, a doctor needs to pay attention to the fact that the surgical instrument can slowly extend out of the front end part of the endoscope and cannot suddenly extend out of the front end part of the endoscope during quick insertion, the sudden extension may cause that a forceps head or a needle head at the front end part possibly damages a mucous membrane at the front end part of the endoscope, and at the moment, the main attention of the doctor is focused on an imaging system of the endoscope and is not focused on the insertion of; the existing medical tools matched with the endoscope clamping channel are as follows: the medical instruments matched with the endoscope channels, namely biopsy forceps, foreign body forceps, a spraying catheter, an endoscope injection needle, a basket, a needle-shaped knife, an electric snare, various endoscopic incision knives, a heat probe, a heat hemostatic forceps, a laser fiber, an argon cutter catheter, a microwave probe, a metal clamp, a nylon rope and the like, which are all commonly used have no reminding function that the instruments are about to extend out of the front end part of the endoscope.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a medical tool matched with an endoscope channel, namely biopsy forceps, foreign body forceps, a spraying catheter, an endoscope injection needle, a basket, a needle-shaped knife, an electric snare, various endoscopic incision knives, a heat probe, a heat hemostatic forceps, a laser fiber, an argon cutter catheter, a microwave probe, a metal clip, a nylon rope and the like, and the medical tool has a reminding function when the medical tool is about to stretch out the front end part of the endoscope.

The technical scheme of the utility model is, including handle, outer tube and medical instrument's head function piece, the outer tube diameter slightly is less than the endoscope pincers way, and outer tube length is longer than the length that the endoscope pincers said, is equipped with the touch at the surface of outer tube and reminds the section, and the touch reminds the section at the nearly handle end of outer tube, indicates that the outer tube inserts the endoscope pincers way and is close one section outer tube that the isometric position with endoscope length begins. The convex-concave tactile reminding section arranged on the section of the outer tube can not cause the unsmooth insertion of the outer tube. When the doctor touches the touch reminding section, the doctor knows that the front end of the medical tool is extended out of the sight glass quickly.

The tactile reminding section is that the surface of the outer tube is provided with concave or convex distribution on the outer tube, and the tactile reminding section is 2-25 cm.

The tactile reminding section is 3-10 cm.

Other areas on the surface of the outer tube are smoothly distributed, and the concave or convex points or rings of the tactile reminding section are only 0.05-0.3 mm higher or lower than the surface, so that the outer tube of the instrument can not enter the front end of the endoscope through the endoscope clamping channel.

The size of the concave or convex is 1-4 mm, and the concave or convex is distributed on the semi-column or full-column surface of the outer tube.

Concave pits, convex points, convex blocks, concave rings or convex rings are distributed on the tactile reminding section.

As a conduit for an endoscope to communicate the body cavity with the exterior, the forceps channel is the only way for all endoscopic accessories (or surgical instruments) to enter the body cavity. These accessories include biopsy forceps, foreign body forceps, spray catheters, endoscopic injection needles, baskets, needle knives, snare instruments, various endoscopic undercutters, thermal probes, thermal hemostats, laser fibers, argon knife catheters, microwave probes, metal clips, nylon cords, and the like. Taking a gastroscope as an example, the length of the insertion part of the gastroscope is 1100mm, and the diameter of the forceps channel is 2.8 mm. In order to facilitate insertion of the endoscope into the body cavity, the endoscopic accessory is also extremely slender, having a catheter-like shape. This determines that the most normal task for the endoscopist is to repeatedly insert, remove, reinsert, and remove the attachment. In a conventional gastroscopy, if 4 tissues are to be removed from the patient's stomach, the biopsy forceps are inserted and withdrawn 4 times.

When the accessory is inserted, an endoscope doctor holds the endoscope operation part with the left hand and repeatedly sends the accessory into the endoscope channel with the right hand, and the two eyes look at the display screen to observe whether the accessory extends out from the head end of the endoscope or not. In order to prevent the accessory from suddenly extending out from the head end of the endoscope to damage the mucous membrane of the body cavity, an endoscope doctor mostly adopts a method of 'filling after quickly and running in small steps', namely, the action is quick when the endoscope is just inserted, the insertion is slow almost as soon as the endoscope is inserted, the feeding frequency is high, and the feeding stroke is short. Even in this case, the user forgets to take in the hand, the head end of the attachment suddenly protrudes to a large extent, and the mucous membrane of the body cavity is injured. Of course, the endoscopist can also look down at the remaining amount of the accessory outside the endoscopic forceps channel, or mark the corresponding part of the accessory, but the attention of the endoscopist can be lost from the display screen.

The utility model discloses the corresponding position of planning at the insertion type scope annex through scope pincers way sets up the sense of touch and reminds the section. The scope doctor can insert the annex fast, by a wide margin, and when he inserted the hand touch of annex and the touch on the annex reminds the section, can slow down the insertion speed, reduce the range of inserting because the annex is about to stretch out from the scope head end, will avoid haring the mucous membrane. Without the need for the doctor to pay attention away from the display screen, thereby increasing work efficiency and reducing operational damage.

Has the advantages that: the utility model provides a medical apparatus matched with an endoscope channel, which has the function of utilizing touch sense to remind the front end part of an endoscope. The external tube of the instrument can enter the front end of the endoscope (or be pulled out) through the endoscopic forceps channel without influencing the main attention of a doctor, and the forceps head or the needle head at the front end can accurately and slowly extend out of the front end of the endoscope under the control of the doctor when the endoscope is inserted, so that the mucous membrane at the front end part of the endoscope can not be damaged, and the operation efficiency of the doctor is also improved.
