Abstract
The utility model provides a kind of dilating drainage external member, including one group of expansion pipe, one group of expansion pipe includes the expansion pipe that several length are identical and diameter is different, the expansion tube head is point, the dilating drainage external member further includes sheath, and the sheath has strip shaped opening along its length, and diametrically section is excellent arcuate structure to the sheath, described sheath one end is fixed with removing handle, has non-skid band on the removing handle.The utility model structure is simple, and design rationally, can effectively take out sheath without tearing manually, facilitate sheath and other fractures, effectively improve procedure efficiency.
Description
Technical field
The utility model relates to medical instrument especially technical field of surgical instruments more particularly to a kind of dilating drainage sets
Part.
Background technique
Dilating drainage external member is a kind of clinically common Minimally Invasive Surgery instrument.Clinically mainly pass through expansion with well
Pipe be implanted into the position that human body needs to drain or establish channel under the guiding of seal wire, and removal expansion is managed, by cannula body,
Drainage catheter is placed in or is implanted into for surgical instrument.Since it can be retained in human body whithin a period of time, it can effectively mitigate trouble
The pain of person and the workload of nursing staff.Dilating drainage external member used at present, generally comprise Group Design expansion pipe and
Sheath composition.Sheath is generally peeling sheath, after expansion pipe is successively expanded from trumpet to large size, other instruments with sheath
(such as drainage tube etc.) enters tissue, needs to take out sheath later, will be in other instrument deployeds and human body.Due to minimally invasive hand
In art, need to generally be connected with corresponding medical device after other instruments, when taking out sheath, not can guarantee human body and medical device it
Between have and fully meet taking-up space on sheath length direction, generally require manual pulled sheathing canal.And due to the material of sheath
Limitation, manual tearing process need medical staff using large force, and tearing is not easy, and affect procedure efficiency.
Utility model content
Technical problem to be solved by the utility model is: the deficiency in order to overcome the prior art, the utility model provides one
Kind can effectively take out sheath without tearing manually, facilitate sheath and other fractures, effectively improve the expansion of procedure efficiency
Drainage device.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of dilating drainage external member, including one group
Expansion pipe, one group of expansion pipe includes the expansion pipe that several length are identical and diameter is different, and the expansion tube head is
Point, the dilating drainage external member further includes sheath, and the sheath has strip shaped opening, the sheath edge along its length
Diametrical direction section is excellent arcuate structure, and described sheath one end is fixed with removing handle, has on the removing handle anti-
Slide strips.
Further, the angle of excellent arcuate structure is preferably 270 °.
Further, removing handle is an integral molding structure with sheath.
Further, one group of expansion pipe includes five expansion pipes that length is identical and diameter is different.
During surgery, using expansion pipe from tissue is as low as expanded greatly, implantation will be then needed to be retained in people intracorporal
Instrument outsourcing enters human body in sheath, from the practical expansion pipe place of expanding, and after instrument implantation in place, pulls removing handle, side
Unsheathing tube edge along instrument length direction and removing handle reversely makes power along the opening of the excellent arcuate structure of sheath, by sheath from device
It is stripped down on tool.Handle is removed by pulling, instrument and sheath are removed from sheath opening, it can be complete without tearing sheath
At lock out operation, rapid operation and convenient can effectively improve procedure efficiency.
The utility model has the beneficial effects that dilating drainage device provided by the utility model, structure is simple, and design is closed
Reason, can effectively take out sheath without tearing manually, facilitate sheath and other fractures, effectively improve procedure efficiency.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view of the utility model optimum embodiment.
Fig. 2 is the top view of the utility model optimum embodiment.
Fig. 3 is the cross-sectional view of A-A in Fig. 2.
1 in figure, expansion pipe 2, sheath 3, opening 4, remove handle 5, non-skid band.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of dilating drainage external member as shown in Figure 1 to Figure 3 is the utility model optimum embodiment, including one group of expansion
Pipe 1, one group of expansion pipe 1 include the expansion pipe 1 that several length are identical and diameter is different, and 1 head of expansion pipe is
Point.One group of expansion pipe 1 includes five expansion pipes 1 that length is identical and diameter is different, expansion 1 model of pipe be preferably F8,
F10、F12、F14、F16。
The dilating drainage external member further includes sheath 2, and the sheath 2 has strip shaped opening 3, the sheath along its length
Diametrically section is excellent arcuate structure to pipe 2, and further, the angle of excellent arcuate structure is preferably 270 °.
Described 2 one end of sheath is fixed with removing handle 4, and removing handle 4 is an integral molding structure with sheath 2.In order to mention
High charge stripping efficiency avoids skidding when removing, and removing has non-skid band 5 on handle 4, frictional force can be effectively increased, convenient for pinching
Strip operation is carried out by removing handle 4.Non-skid band 5 can be evenly spaced strip or dotted according to actual use Demand Design.
During surgery, using expansion pipe 1 from tissue is as low as expanded greatly, implantation will be then needed to be retained in people intracorporal
Instrument outsourcing enters human body in sheath 2, from practical 1 place of expanding of expansion pipe, after instrument implantation in place, pulls removing handle 4,
Edge instrument length direction extraction 2 side of sheath, which will remove handle 4, makes power along the reversed of opening 3 of the excellent arcuate structure of sheath 2, by sheath
Pipe 2 is stripped down from instrument.Handle 4 is removed by pulling, instrument and sheath 2 are removed from the opening of sheath 23, without tearing
Opening sheath 2 can be completed lock out operation, rapid operation and convenient, can effectively improve procedure efficiency.
The dilating drainage device being designed in this way, structure is simple, and design rationally, can effectively take out sheath without tearing manually
2, facilitate sheath 2 and other fractures, effectively improves procedure efficiency.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
