Description

Technical Field

[0001] This utility model belongs to the technical field of intestinal obstruction treatment devices, and specifically relates to a visual intestinal obstruction treatment device. Background Technology

[0002] Intestinal obstruction is one of the most common surgical acute abdominal conditions. Any obstruction of the passage of intestinal contents due to any cause is collectively referred to as intestinal obstruction. It is a common surgical acute abdominal condition, second only to biliary tract diseases and acute appendicitis in incidence. After onset, it can cause not only local changes in the intestinal tract but also systemic pathological changes. Sometimes, acute intestinal obstruction is difficult to diagnose, and its rapid progression often leads to patient death.

[0003] Intestinal obstruction treatment devices are used to relieve intestinal obstruction in patients. Currently, non-surgical methods for treating intestinal obstruction in clinical practice typically use gastric tubes, intestinal obstruction catheters, etc. However, existing intestinal obstruction catheters inevitably encounter difficulties in passing through the pylorus and accidental balloon rupture, leading to treatment failure and increasing patient suffering.

[0004] Patent CN202010631476.0 discloses an electronic endoscope, comprising an insertion part and an operating part connected sequentially. The insertion part includes a front end and a curved part. The distal end face of the front end has an inclined surface, which intersects with the distal end face of the front end to form a ridge line, which is parallel to the bending direction of the curved part. This invention provides an electronic endoscope that achieves good permeability at low cost for various usage environments, facilitating accurate and rapid access to the obstructed intestines requiring unblocking, thereby clearing the obstruction. However, the camera and illumination units in this invention do not provide an ideal field of view when used in the intestines. Furthermore, due to the small diameter of its curved part, it is not very effective in treating adhesive intestinal obstruction. Since over 80% of small bowel obstructions are mechanical, and over 85% of these are adhesive obstructions, improvements to this endoscope are needed to make it more suitable for treating intestinal obstruction. Summary of the Invention

[0005] This invention provides a visual intestinal obstruction treatment device to solve the technical problems existing in the prior art. It can accurately and quickly reach the intestinal obstruction site and quickly loosen and clear the obstruction.

[0006] This utility model includes the following technical solution:

[0007] A visual intestinal obstruction treatment device includes an operating part, a guide wire, and a guide head. The guide wire is connected to the guide head at its distal end and to the operating part at its proximal end. The operating part controls the bending of the guide head. A circular illumination unit is fixedly mounted at the distal end of the guide head, and a miniature camera is fixedly mounted at the center of the illumination unit. The illumination unit and the miniature camera are housed within a bullet-shaped transparent shell. An expansion structure is provided on the outer wall of the guide head.

[0008] Furthermore, the transparent shell is made of epoxy resin adhesive and is integrally formed with the lighting unit, miniature camera and transparent shell.

[0009] Furthermore, the distal end of the guide wire near the guide head is provided with several liquid outlet holes for rinsing or adding medication during treatment; the outer surface of the guide wire is provided with a hydrophilic coating.

[0010] Furthermore, a developing ring is provided on the outer wall of the illumination unit.

[0011] Furthermore, the center of the guide head and guide wire is the main chamber, and wire harness channels are symmetrically arranged on both sides of the main chamber. Control wire harnesses connected to the operating unit are arranged in the wire harness channels.

[0012] Furthermore, an auxiliary channel and a cable channel are also provided on the outer side of the main cavity. The cable channel contains cables connecting the lighting unit and the miniature camera to the operating unit. The cables include electrical wires, data cables, etc.

[0013] Furthermore, the distal end of the operating unit is connected to a guide wire and an infusion connector, the proximal end is provided with a rotating handle, and a data connection port is provided on the side; the infusion connector is connected to the main chamber, and flushing and drug administration are performed through the infusion connector. The data connection port includes a USB connection port and an HDMI connection port.

[0014] Furthermore, the expansion structure is an arc-shaped expansion block made of water-absorbing material, and the expansion blocks are evenly distributed on the outer wall of the guide head. When relieving intestinal obstruction, the shape of the expansion blocks can be used to clear the obstruction.

[0015] Furthermore, the expansion structure is an inflatable air bladder, and the position of the intestinal expansion can be controlled by inflating and inhaling the air bladder when relieving intestinal obstruction.

[0016] Furthermore, the inflatable airbag is connected to an air tube, and the other end of the air tube is connected to the airway connector of the operating unit.

[0017] The advantages and positive effects of this utility model are as follows:

The transparent shell 6 is formed by curing epoxy resin adhesive, and the illumination unit 4, the miniature camera 5, and the transparent shell 6 are integrally molded. The miniature camera 5 protrudes from the illumination unit 4, providing a larger field of view compared to traditional structures, facilitating observation of the intestinal wall. A contrast ring 7 is provided on the outer wall of the illumination unit 4, and an expansion structure is provided on the outer wall of the guide head 3. like Figure 2The diagram shows the expansion block 8 in its water-absorbing and swelled state. The expansion structure is an arc-shaped expansion block 8 made of a water-absorbing material such as superabsorbent resin. The expansion blocks 8 are evenly distributed on the outer wall of the guide head 3. When relieving intestinal obstruction, the shape of the expansion blocks 8 can be used for unblocking. After expanding inside the intestine, the diameter of the expansion block 8 increases, which can help separate and unblock mild adhesions in intestinal obstruction. Furthermore, after the expansion block 8 expands to create a certain space, the imaging effect of the front-end miniature camera 5 is also improved. When the obstruction is complex, this device can also be used in conjunction with an intestinal obstruction catheter to achieve ideal therapeutic results.
