Description
Technical field
Strangled the present invention relates to one kind for alimentary canal, respiratory tract polyp or tumour and remove, burn, cutting, synchronously realize blood coagulation
The medical apparatus of function.Belong to medical instruments field.
Background technology
Conventional that alimentary canal, respiratory tract polyp or tumour are extractd under scope using electric snare, its principle is profit
Hyperpyrexia is produced into contact with the tissue of snare with high frequency electric and be cauterized cut-out, completely rapidly cut off polyp and thoroughly stop
Blood.
Traditional electric snare excision polyp, is usually associated with art/postoperative hemorrhage.For anticoagulant therapy patient, carry out
Operation consent generally requires to withdraw anticoagulation, and this further increases the risk of bleeding.Conventional intraoperative hemorrhage, or use argon gas jet pipe electricity
Solidifying hemostasis；Or spray line or injection needle are used, sprayed to bleeding part or inject Hemostatics；Or pressed from both sides using apparatuses such as hemostatic clamps
Hold bleeding part hemostasis, etc..
In addition, for that in operation, may there are the edge tissues of part to remain and edge oozing of blood.Traditional electric snare, it is right
Above-mentioned situation can not implement excision and hemostasis operation.Special apparatus is now changed, aforesaid operations are completed such as needle-like knife.
Grant number is CN2049096320U patent, invented it is a kind of can be while be used for TURP and the device of coagulation, can
To solve the above problems.But the technology is the apparatus of snare direction fixed, for alimentary canal or respiratory tract different spatial
Polyp or tumour when being treated, it is necessary to so that snare is able to alignment target lesion by way of rotating scope direction, deposit
In certain not convenient property of operation.
The content of the invention
In order to solve the above mentioned problem of prior art, the present invention provides a kind of rotary-type medical TURP and electric coagulation device, hand
During art, it not only conveniently can realize to strangle alimentary canal, respiratory tract polyp or tumour and remove, burn, cutting, synchronous realization is solidifying
Blood, and margin residual tissue can be cut off and edge oozing of blood position progress electric coagulation hemostasis.With function is integrated, structure is simple
It is single, the characteristics of easy to operate, shorten operating time and lower operating difficulty, save medical expense.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of rotary-type medical TURP and electric coagulation device, including snare, connecting tube, insulating sleeve, outer sheath, coagulation electricity
Pole, rotating shaft, handle set, sealing ring, conduit, runner, ventilating joint, energization joint and handle；Outer sheath near-end connects with handle set
Connect, insulating sleeve and coagulating electrode are both secured to outer sheath distal end inwall, and snare is connected by connecting tube and rotating shaft distal end, rotating shaft
Near-end is connected with distal end of catheter, and sealing ring and runner are arranged on handle set relevant position, and conduit is from handle set, sealing ring and turns
Through being connected again with the energization joint on handle in the middle of wheel, ventilating joint is provided with handle set, handle is assemblied in hand
Handle seat is upper and reciprocable, snare, connecting tube, insulating sleeve, outer sheath, coagulating electrode, rotating shaft, handle set, sealing ring, leads
Pipe, runner, handle are installed each along outer sheath length axes direction.Handle is axially moved along handle set, control snare stretch out or
Into outer sheath.Wherein：Handle set axially has through hole and has the runner groove of radial opening between ventilating joint.Runner groove
For laying runner.Handle block hole passes through for conduit, through hole internal diameter 0.1mm more than bigger than catheter outer diameter, enough cooperations
Gap can ensure conduit flexible rotating in through-holes.
Handle set runner groove distal face is toward having the circular groove consistent or bigger with sealing ring external diameter, and circular groove on distal direction
Do not connected with ventilation interface cavity.Circular groove is used to install a sealing ring to 20 quantity, and particular number is according to actual conditions
It is determined that.Sealing ring is loaded in circular groove and sealing ring proximal end face is fitted with runner distal face, runner proximal end face and runner groove near-end
Face is fitted, and runner distal face is not contacted with runner groove distal face.Above-mentioned guarantee runner can be with persistent pressure on sealing ring.Sealing
Loop material is the one or more combination in silica gel, rubber, TPE, PVC, PTFE, and material has certain elastic deformability.
Internal diameter of the seal ring and catheter outer diameter difference are -0.8mm ~+0.8mm, both even if there is gap also will not be especially big.Pass through runner
Distal face crush seal circle proximal end face, sealing ring deforms, and internal diameter diminishes, so that remote in conduit, sealing ring, handle block hole
End part, the luminal portion formation sealing of ventilation interface, it is ensured that argon gas does not leak toward the flowing of outer sheath distal direction.In addition, above-mentioned
Structure can ensure the sealing ring deformable seal under runner compression always, even if driven by rotating wheel conduit and rotating shaft rotation remain to keep
Sealing state.
Runner endoporus is non-circular, such as one kind in kidney-shaped, oblateness, water-drop-shaped, polygon.Matched conduit
Part is also fabricated to shape consistent therewith so that non-slip in driven by rotating wheel conduit rotary course.
Rotating shaft material is stainless steel or NiTi.Rotating shaft material requirement possesses certain rigidity, it is ensured that snare is in tortuous disappear
Change and remain to smoothly release or reclaim in road, possess certain synchronous rotary performance while also requiring that, it is ensured that snare can cooperate with runner
Synchronous rotary.
Tube material is stainless or ferronickel or copper.The conduit of metal material can ensure that good electric conductivity and mechanics are strong
Degree.
Rotating shaft and catheter material surface are coated with the coating of reduction frictional resistance.Coating chemically reacts with material surface
As a material surface part, or do not chemically react with material surface, only distinct faces coating presence.The former coating material
Material composition should select type siloxane, and the latter needs to select organic silicon.
Further, it is the geometric figure with internal diameter, external diameter on the sealing ring circumferencial direction section.Internal diameter and conduit
Coordinate, external diameter coordinates with handle set circular groove.Can be many for circular, cylindrical, square, double circular ring types etc. on circumferencial direction section
Plant geometry.
Further, the runner proximal end face has annular recess, and depth of groove is not less than 0.1mm.The effect of annular groove,
It is to reduce the frictional force of runner proximal end face and handle set runner groove proximal end face.Two plane contact areas are small, and runner rotates when institute
It can also be declined by frictional force.
Further, the runner largest contours protrude handle seating face, and radially there is the rib of more than 1 outer surface
Shape projection.Above-mentioned design can increase operator's feel, and be skidded when preventing from rotating between hand and runner.
Compared with the existing technology the beneficial effect of above-mentioned technical proposal is taken to be compared with, the present invention：In surgical procedure, one is used
Device is planted, not only conveniently can realize to strangle alimentary canal, respiratory tract polyp or tumour and remove, burn, cutting, synchronously realize blood coagulation,
And margin residual tissue can be cut off and edge oozing of blood part carries out electric coagulation hemostasis.It is integrated, simple in construction with function,
Easy to operate the characteristics of, shorten operating time and lower operating difficulty, save medical expense.
