Abstract
The utility model relates to a universal radial sealing ring used for puncture outfits; the edge of an inner hole of the sealing ring is provided with a high-strength area, and a low-strength area is arranged between the outer edge and the high-strength area. When a surgical instrument is inserted into the inner hole of the high-strength area, the high-strength area can be tightly adhered to the surgical instrument; when the surgical instrument moves or shakes, the low-strength area deforms but the high-strength area can be tightly adhered to the surgical instrument and does not deform, so as to keep quite good dynamic sealing. The structure realizes the random replacement of surgical instruments with the diameter of 12mm, 10mm and 5mm, which is convenient for surgeries.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to the perforator that uses in micro-wound surgical operations such as peritoneoscope, thoracoscope and the sealing ring on the perforator.
Background technology
Micro-wound surgical operation such as peritoneoscope, thoracoscope has obtained application more and more widely in modern medicine, for fear of nosocomial infection, the consumption of the disposable puncture device that uses in the micro-wound surgical operation such as peritoneoscope, thoracoscope (Trocar) is also increasing, on the basis that guarantees serviceability, simplified structure, reducing cost becomes the improved direction of perforator.
The hermetically-sealed construction of the perforator of prior art is made up of radial direction seal ring and check valve.Wherein check valve has two kinds, one is spring pressuring plate formula structure (with reference to figure 1, Fig. 2), promote the sealing of baffle plate compressing silica gel sealing loop-shaped by spring leaf, form sealing ring by spring leaf, baffle plate, silica gel sealing ring, spring leaf, baffle plate adopt the rustless steel manufacturing usually, the sealing ring of this form often uses in the perforator that nonexpondable metal is made, and this perforator price is more expensive, and weight is heavier.Over nearly 2 years, needs for suitable disposable puncture device development, developed funnel type silica gel sealing ring (with reference to figure 3, Fig. 4), this funnel type silica gel sealing ring has a through otch of straight line in the bottom of funnel type, utilize the pressure that the carbon dioxide pneumoperitoneum forms in the contractility of silica gel itself and the use, reach the effect of sealing, this funnel type silica gel sealing ring uses in disposable puncture device usually.Radial direction seal ring adopts the garden loop configuration of band centre bore, and to adopt be thick and to the centre bore structure of attenuation progressively by outer rim, this outer rim thick to centre bore progressively the sealing ring of attenuation when operating theater instruments is rocked, reveal the movable sealing weak effect especially easily.For this reason, when the radial direction seal ring of employing prior art uses the operating theater instruments of 5mm on the perforator of 10mm, need to adopt conversion sheath pipe (with reference to figure 5, Fig. 6), this has brought inconvenience for doctor's operation technique.
Thereby the radial direction seal ring of needs improvement perforator, to reach the operating theater instruments that on the perforator of 10mm, can use 10mm, also can use the operating theater instruments of 5mm, and need not to use conversion sheath pipe, reach general purpose.
Summary of the invention
The general purpose type radial direction seal ring that the purpose of this utility model has been to provide a kind of perforator to use, its delicate structure, reliability height, low, the good sealing effect of cost.
The edge of the endoporus of puncture device general purpose type radial direction seal ring is provided with intensity region, and is provided with areas of weak intensity between the outer rim of sealing ring and intensity region.
Further, described puncture device general purpose type radial direction seal ring, the resistance of deformation of intensity region that it is characterized in that described sealing ring is greater than the resistance of deformation of areas of weak intensity.
The thickness of described sealing ring intensity region is greater than the thickness of areas of weak intensity.
Described sealing ring is provided with the areas of weak intensity more than 2 or 2.
The diameter of the endoporus of the intensity region of described sealing ring is between 1mm～5mm, and optimum is between 2.5mm～4.5mm.
Described sealing ring adopts the flexible medical material manufacture.
Further, described flexible medical material is selected from medical silica-gel, medical polyurethane, medical grade rubber.Can adopt high anti-tear medical silica-gel to make the general purpose type radial direction seal ring of this utility model especially.
Described general purpose type radial direction seal ring and check valve are combined into the complete hermetically-sealed construction of perforator.
Further, described complete perforator hermetically-sealed construction includes the general purpose type radial direction seal ring of this utility model more than 2 or 2.
When the hermetically-sealed construction of described perforator includes puncture device general purpose type radial direction seal ring more than 2 or 2, wherein have at least a puncture device general purpose type radial direction seal ring to be arranged near the loam cake of perforator, another puncture device general purpose type radial direction seal ring is arranged near the check valve of perforator, can be on the top of check valve near the position of check valve, also can be in the bottom of check valve near the position of check valve.
In addition, this utility model also comprises perforator, and this perforator has adopted the general purpose type radial direction seal ring of this utility model.
Because the general purpose type radial direction seal ring of this utility model has adopted the intensity region of interior bore edges, and this special structure that between the outer rim of sealing ring and intensity region, is provided with areas of weak intensity, after operating theater instruments is inserted the intensity region endoporus, intensity region can be close to operating theater instruments, when operating theater instruments is rocked, areas of weak intensity distortion, and intensity region can be close to operating theater instruments and not deform, thus kept reasonable dynamic seal (packing).Adopt the general purpose type radial direction seal ring of this utility model, can insert the operating theater instruments that diameter is 10mm or 5mm arbitrarily, and keep good dynamic sealing performance.This structure can also realize that diameter is any replacing between 12mm, 10mm and the 5mm operating theater instruments; Operating theater instruments between 15mm, 12mm, 10mm and the 5mm is changed arbitrarily; And 10mm, 12mm and 15mm between operating theater instruments change arbitrarily.
The puncture device general purpose type radial direction seal ring of this utility model, delicate structure, reliability height, low, the good sealing effect of cost.The perforator that adopts sealing ring described in the utility model to make after operating theater instruments passes in and out 1000 times repeatedly, still can keep good sealability.The general purpose type radial direction seal ring of this utility model can be widely used in the perforator of micro-wound surgical operations such as peritoneoscope, thoracoscope.
