Abstract
The utility model discloses a blocking clamp of an air-bag type, and the clamp comprises a strip-shaped blocking air bag. One end of the blocking air bag is provided with a blocking hole, and the other end of the blocking air bag is provided with a blocking head. After the blocking head passes through the blocking hole, the cross section of the blocking head in an inflation state is greater than the passing-through area of the blocking hole. An interior air chamber of the blocking air bag is communicated with an inflation pipeline. The clamp provided by the utility model achieves the purposes of extruding a blood vessel and blocking a blood flow through the inflating of the blocking air bag. Compared with the prior art, the clamp provided by the utility model is made of flexible materials, and is more convenient to enter into or come out of a minimally invasive surgery channel. Aiming at various types of blood vessels in different sizes, the pressure of the air bag can be adjusted through inflation and air exhaust. Meanwhile, the clamp is convenient to adjust the blocking position. The surface contact and the precise pressure control enable the damage to the walls of the blood vessels to be reduced to the maximum extent during blocking, thereby perfectly reflecting the idea of precise surgery. When the clamp provided by the utility model is used for operation, there is no need of a dedicated clamping machine. The clamp is made of high polymer materials, so the clamp has the cost advantage.
Description
Technical field
This utility model belongs to surgical operating instrument, is specifically related to carry out for human vas in a kind of operation process the gasbag-type blocking-up folder of interim blocking-up.
Background technology
The interim blocking-up of blood vessel is widely used in various surgical operations, for example hepatotomy, kidney excision etc. common operation, amount of bleeding when blood vessel blocking can reduce organ removal, the blocking-up of vessel branch simultaneously can judge the edge of organ removal, therefore in multiple operation, the use of vascular occlusion clamp or blood vessel blocking folder is comparatively general.Along with the development of Wicresoft's endoscopic technic, increasing open surgery all can operate by laparoscopic surgery, comprising that the more complicated operations of series such as hepatectomy, the nephrectomy, pneumonectomy are succeeded under peritoneoscope implements, these complicated laparoscopic surgeries require higher for the control of amount of bleeding, therefore under peritoneoscope, blood vessel blocking also becomes an important technology ingredient.
At present conventional vascular blocking device is all that the direct folder that carries out blood vessel by metal pliers or metal clip closes, and has following weak point: 1. metal pliers or metal clip easily cause damage to blood vessel wall in clinical practice, causes postoperative thrombosis; 2. the pressure of metal pliers or metal clip is just fixing afterwards in production, no matter type, size, the pressure of blood vessel, the pressure producing when its application is constant, may cause for the little blood vessel of pressure and apply the situation that too much pressure causes the unnecessary damage of blood vessel, and for the large blood vessel of pressure, vascular clamp pressure causes the situation that bloodstream blocking is incomplete not; 3. the metal pliers or the metal clip that use at present all have larger clamp handle or chuck, take up space larger, for operation dissection, separation and organ removal operation are caused a lot of inconvenience and easily caused vascular clamp to get loose by mistake tractive; 4. all kinds of vascular clamps under current peritoneoscope have still been continued to use the metallic blood vessel sandwiched meter of conventional therapy, exist volume large, place difficult problem by peritoneoscope sheath pipe, because metal current folder need to be clamped and operate at intraperitoneal by metal applicator, more exist under peritoneoscope operations such as turning to, clamp, unclamp, adjust position to realize the fatal shortcoming of difficulty.
Utility model content
This utility model blocks for existing metal pliers or metal clip the technological deficiency that pipeline exists in operation, and provide one both easy to operate, the apparatus that can realize again noinvasive blocking-up blood vessel, has great importance and application prospect for open and carrying out of laparoscopic surgery.
This utility model adopts following technical scheme to realize: gasbag-type blocking-up folder, comprise the blocking-up air bag of strip, described blocking-up air bag one end is provided with blocking-up hole, the other end is provided with blocking-up head, described blocking-up head can be through blocking-up hole, and the maximum cross-section area of described blocking-up head is greater than the area that passes through in described blocking-up hole; The inner plenum of described blocking-up gas enclosure capsule is communicated with loading line.
The inner chamber of described blocking-up head is the part that described blocking-up gas enclosure capsule inner plenum is communicated with, between described blocking-up head and blocking-up gas enclosure capsule, be communicated with by a cervical region, the cross-sectional area of described cervical region is more than or equal to passing through area and being less than the described cross-sectional area of blocking head of described blocking-up hole.
Described blocking-up head is provided with the handle of guiding through blocking-up hole.
The outer wall thickness of described blocking-up gas enclosure capsule is less than 1mm, comprise one deck elasticity inner liner composition, the material of elasticity inner liner adopts medical grade rubber or thermoplastic elastomer (TPE), outside described elasticity inner liner, can wrap up one deck elastic fabric layer is set, the material of described elastic fabric layer can adopt elastic non-woven cloth etc.
This utility model is by inflating to blocking-up gas enclosure capsule the effect that reaches extruding blood vessel and block blood vessel, effectively solve several defects of conventional metals vascular clamp: 1. air bag is to realize by the contact of face to the extruding of blood vessel, air bag is flexible structure simultaneously, and the pressure of air bag can be adjusted to optimum state according to blood vessel situation, the damage to blood vessel while making to block reaches minimum degree; 2. airbag aeration front volume is little, in laparoscopic surgery, conveniently enters abdominal cavity by peritoneoscope sheath pipe; 3. this utility model does not have the structure such as binding clip or clamp handle, has dwindled occupying of space, and for operation is enclosed, vascular anatomy separates and organ removal provides convenience; 4. inflation can be inflated by the pneumoperitoneum aerating device under peritoneoscope, and open surgery can be inflated by syringe, and it is convenient to realize, and does not need extras; 5. this utility model is realized blocking-up repeatedly and the release of blood flow by repeatedly inflating venting, does not need mobile vascular clamp itself, and traditional metallic blood vessel folder of avoiding repeatedly folder closes blood vessel injury and the operation inconvenience that blood vessel brings; 6. this utility model is macromolecular material, compares with metal clip, and the situation that energy conduction causes blood vessel injury can not occur in the time that operation is used electric knife homenergic apparatus
From the above mentioned, this utility model adopts such scheme, perfectly solve the variety of issue that at present interim blood vessel blocking faces, in the middle of concrete enforcement, the concept of precisely perform the operation concept and personalized medicine is implemented to blood vessel and block in the middle of concrete operations here temporarily, have learning value and practical value.This utility model is by realizing cleverly the ingenious combination of air bag and block function, and except widely used blood vessel blocking, other passages of every inside of human body or the interim blocking-up of histoorgan also can be suitable for completely.The flexible high molecular material of this utility model use is simultaneously its main material, compares the clip that present stage is used precious metal material, has economic worth.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
