Technical Field
The present invention relates to a device for applying pressure or stopping bleeding in a body cavity, in particular near the fundus of the digestive tract.
Background
About 120 ten thousand people die each year due to cirrhosis in the world, and the number of people increases year by year, most of the causes are esophageal gastric fundus varices rupture and bleeding caused by cirrhosis, and the common hemostasis methods are medicines, instruments, interventional operations, open abdominal operations and the like. For acute stage treatment of acute severe hemorrhage, the currently international preferred common means is still a three-lumen two-balloon tube, also known as a Sengstaken-Blakemore tube or a Minnesota tube, which is used by a small number of doctors to stop bleeding by compression, using a Linton-Nachlas tube (only one gastric balloon of about 500ml, no esophageal balloon). Although the hemostatic devices described above have long played an important role in clinical most esophageal fundus varices rupture bleeding, many problems have been found during use, such as common complications including esophageal fundus mucosa necrosis, mucosal ulcers, secondary avulsion bleeding upon removal, rare complications including esophageal rupture, choking airways, and the like, other adverse aspects including placement of tubing, compression inefficiency, difficulty in compression adjustment, balloon rupture, interference with further gastroscopy, and the like.
In addition, as shown in FIG. 1, the fundus 60 of the human digestive tract is immediately adjacent to the distal end of the esophagus 50. When bleeding near the fundus, the local pressure of existing balloon or other hemostatic devices is typically not adjustable, although compression hemostasis may be achieved by accessing the site. Thus, there is a need for a hemostatic device or apparatus that applies pressure to the fundus hemorrhage site during hemostasis that can be adjusted accordingly as needed during hemostasis.

As shown in fig. 2, the medical body cavity internal pressure applying device of the present invention includes a cylindrical holder 3 and an openable and closable umbrella 5, and a connection transition portion 4 therebetween.
The tubular stent 3 is generally cylindrical in outer profile, formed with a hollow channel and radially expandable. The cylindrical stent 3 is preferably made of an elastic material such as a shape memory alloy elastic material. In addition, the illustrated cylindrical holder 3 is formed in a net cylinder structure, so that low-pressure interval compression can be provided.
The openable and closable umbrella 5 has an upper umbrella tip and a lower openable and closable end. The top end of the umbrella is provided with an opening and is communicated with the hollow channel of the cylindrical bracket 3 through the hollow connecting transition part 4. When the tubular stent 3 is in the expanded state, the outer diameter of the connection transition section 4 is smaller than the outer diameter of the tubular stent. The connection transition 4 is illustrated as being shaped like a truncated cone with its tapered end facing the tip of the umbrella 3.
The openable and closable umbrella 5 includes a plurality of main ribs 9, a plurality of first branch ribs 7, a plurality of second branch ribs 8, and a fixing rod 6.
The main rib 9 converges toward the top end of the openable and closable umbrella 5 in the opened state of the openable and closable umbrella. The main rib 9 may be made of a suitable material such as titanium or may be made of a shape memory alloy elastic material. The main rib 9 may be formed in a flat strip shape. A plurality of perforations may be further formed in the flat, elongated main rib 9. The length of the main rib 9 can be about 9 cm.
An umbrella cover or an umbrella film 10 is attached to the main rib 9, and the umbrella film 10 can be made of medical polymer materials or human body absorbable and degradable materials. Although not shown, the umbrella membrane 10 can also employ a mesh or mesh membrane to further provide low pressure interval compression. The outer periphery of the canopy 10 may extend slightly beyond the ends of the main ribs 9 to provide soft edge protection.
In addition, the tubular stent 3 may be coated or attached with a medical polymer or biomaterial film (not shown) to reduce irritation to the esophagus 50. In this case, the umbrella film 10 may be integrally formed with the tubular holder film as an elastic film or an elastic mesh film.
The illustrated fixing bar 6 has an upper first end arranged adjacent to the umbrella tip of the openable and closable umbrella 5 and a lower second end arranged adjacent to the open and closed end of the openable and closable umbrella 5. The length of the fixing rod 6 may be about 5 cm.
Each first branch rib 7 has a proximal end fixedly connected to the first end of the fixing rod 6 and a distal end extending towards the top end of the umbrella and fixedly connected to the corresponding main rib 9. Thus, the fixing rod 6 and the main rib 9 are fixed to each other by the first branch rib 7. The first branch rib 7 may be formed in a round bar shape, and the length may be about 4 cm.
Each second branch rib 8 also has a proximal end and a distal end, the proximal end of which is longitudinally slidably connected to the second end of the fixing rod 6 and the distal end extends towards the top end of the umbrella and is fixedly connected to the corresponding main rib 9. The second branch rib 8 may be formed in a round bar shape, and the length may be about 6 cm. Both the first branch rib 7 and the second branch rib 8 can be made of shape memory alloy elastic materials.
The connection point of the first branch rib 7 and the main rib 9 is closer to the top end of the umbrella than the connection point of the second branch rib 8 and the main rib 9, so that the connection point of the first branch rib 7 forms a first inner ring and the connection point of the second branch rib 8 forms a second outer ring. An included angle of about 40 degrees can be formed between the first branch umbrella rib 7 and the fixed rod.
A plurality of longitudinal runners (not specifically shown) are circumferentially spaced around the second end of the securing rod 6 to receive the proximal end of a corresponding second branch rib 8. A series of stop mechanisms, such as slot diameter constrictions 12, may be provided longitudinally (up and down in the illustration) on each runner to stop the proximal end of the second branch rib 8 sliding thereto. The proximal end of the second branch rib 8 may in this case preferably be formed as an expansion head structure, such as a half ball head. The longitudinal sliding grooves are preferably provided as blind grooves formed on the circumferential wall of the solid fixing bar 6 in order to avoid entanglement between the adjustment wires 1, which will be described below.
In order to facilitate the adjustment of the longitudinal sliding of the proximal end of the second branch rib 8 along the fixing rod 6, a plurality of adjustment wires 1 may be used, wherein one end of each adjustment wire 1 is connected with the proximal end of the second branch rib 8, and the other end extends out of the opening of the top end of the openable and closable umbrella 5 and the hollow channel of the tubular bracket 3. In order to prevent scattering of the adjustment wires 1 and possible damage to the digestive tract, a large part of these adjustment wires 1 (referred to as their length) may be accommodated in a hose 11.
As shown in fig. 3, the medical body cavity internal pressure applying device of the present invention may further include a removable sleeve or a removable cartridge 2 which is externally fitted over the openable and closable umbrella 5 and the cylindrical holder 3 to be maintained in a closed state or a contracted state, and automatically releases the openable and closable umbrella 5 and the cylindrical holder 3 to be brought into an open state or an expanded state after being removed. Those skilled in the art will appreciate that any other suitable means may be employed to release the umbrella 5 and the barrel 3 to an open or expanded condition.
The use and operation of the medical body cavity internal pressure applicator of the present invention in the vicinity of the fundus of the digestive tract is briefly described below.
Firstly, the device with the sleeve 2 is delivered to the vicinity of the fundus 60 of the alimentary canal through the oral cavity or the nasal cavity, the sleeve 2 is extracted after the position is determined through the ultrasonic wave at the side of the x-ray or the bed, at the moment, the tubular bracket 3 and the openable and closable umbrella 5 are automatically expanded or normally opened, the whole device is clamped or positioned at the corresponding positions of the esophagus 50 and the fundus 60 due to the relatively reduced outer diameter of the connecting transition part 4, and the varicose veins at the position are pressurized to stop bleeding. Since the entire device is formed with hollow channels running up and down, other examinations such as gastroscopy can still be performed at this time. In addition, the hemostatic device of the present invention may even be subsequently left in the patient for a short period of time to maintain its hemostatic effect without affecting its normal life.
If the pressure applied by the adjusting device to a place near the fundus of the stomach is needed, the corresponding adjusting wire 1 is pulled upwards, so that the proximal end of the second branch rib 8 connected with the adjusting wire is driven to slide upwards along the longitudinal sliding groove arranged on the outer circumference of the fixed rod 6 until the groove diameter narrowing part 12 at the height corresponding to the needed pressure is stopped at the groove diameter narrowing part.
In addition, the pressure of a plurality of directions around the umbrella surface of the openable umbrella 5 can be respectively adjusted by sequentially adjusting different adjusting wires 1, so that the curved vein of the whole umbrella surface on the surface of the gastric fundus mucosa is approximately and completely attached and pressed, and the full hemostasis effect is achieved.
