When inner core is connected with hole head, between head leading section, hole and operating forceps, be provided with exterior seal ring again;
---the length of described overcoat is less than the total length of inner core.
Feature of the present invention: the overcoat causing isolation when winning pathological changes intestinal segment owing to being provided with between it and intestinal inwall, this just above-mentionedly causes this Patient cells (such as: tumor cell) to create condition in healthy intestinal section plantation recurrence because of anus extruding pathological changes intestinal for being avoided.
Accompanying drawing illustrates:
Fig. 1 illustrates structure of the present invention;
Fig. 2 illustrates critical component of the present invention " overcoat " and is arranged on situation in intestinal;
Fig. 3 illustrates the state during pathological changes intestinal segment in intestinal under taking-up cutting.
1: overcoat; 2: inner core; 3: inner seal ring; 4: mushroom head; 5: hole head; 6: exterior seal ring; Q: pathological changes intestinal segment (such as: the sufferer intestinal having tumor---during operation must by pathological changes intestinal segment complete resection); L: screw thread; L1: the female thread of overcoat; W: the fracture position between the pathological changes intestinal segment cut down and healthy intestinal segment; C: intestinal wall; P: skin; G: anus (junction of intestinal wall and skin) J: operating forceps; A: operation chuck; B: handle of exerting oneself (the same with the using method of scissors handle).
Detailed description of the invention:
Structure composition of the present invention comprises:
One, overcoat 1: its long 15cm, internal diameter 4cm, thick 0.2cm; There is the cannelure that can embed the inner seal ring 3 being connected overcoat 1 and inner core 2 front end of overcoat 1; Having long apart from 0.3cm place, top is 3cm, and wide be the female thread of 0.1cm, and have drawn from rustless steel, before being positioned at healthy intestinal segment during insertion intestinal, to ensure the complete preservation of healthy intestinal segment.
Two, inner core 2: its long 18cm, external diameter 3.8cm, thick 0.2cm, has long 3cm apart from 1.3cm place, top, and wide is the external screw thread of 0.1cm, and have drawn from rustless steel.
Three, inner seal ring 3: it is internal diameter 3.8cm, external diameter 3.9cm, the hollow ring of wide 0.1cm, have drawn from soft rubber, it is mainly used in the sealing in gap between overcoat 1 with inner core 2 (although overcoat 1 is connected with screw thread with heart, but between there is fine gap, easily cause packing less state to exist---be filled with the addition of C O2 to set up operative space during operation).
Four, mushroom head 4: become hemispherical, internal diameter 3.8cm, hollow, have drawn from plastics.
Five, hole 5: become semi-spherical shape, internal diameter 3.8cm, hollow, top central authorities have diameter 0.5cm hole can implantation surgery apparatus, and have drawn from plastics.
Six, exterior seal ring 6: it is internal diameter 0.5cm, external diameter 0.6cm, the hollow ring of wide 0.2cm, porose crown end is fixed on by glue, have drawn from soft rubber, it is mainly used in the sealing in operating forceps J (manual stressed member when it is an operation, easily cause packing less state to exist---be filled with the addition of C O2 to set up operative space during operation) and hole 5.
