Abstract
The invention discloses an outer sleeve for a gastroscope. The whole outer sleeve is in the shape of a hollow tube. The inner diameter of the sleeve is 1.1 cm, the inner circle and the outer circle of the sleeve are not concentric, the sleeve with uneven wall thicknesses is formed, the thickness of the position where the wall is thick is 5 mm, and the thickness of the position where the wall is relatively thin is 3 mm. A washing channel is formed in the position, wherein the wall is thick, in the sleeve wall, and the washing channel extends to the bottom of the outer sleeve from the inlet end of the gastroscope. The position, close to a gastroscope inlet, of the wall where is thin is provided with a water filling pipe. The gastroscope inlet and an inlet of the washing channel are provided with silica gel plugs, and the silica gel plugs are covered with cross-shaped openings in the centers. On one hand, the washing channel in the outer sleeve can be used for washing blood, digestive juice, mucus and the like within view, and the view is kept clear; on the other hand, instruments can be delivered, the complexity and the difficulty for endoscope part treatment can be lowered, normal saline and the like are filled through the water filling pipe, the friction force between the outer sleeve and the endoscope can be lowered, the endoscope can move more smoothly and more freely, and the arranged plugs can effectively prevent injected liquid or gastric content from overflowing.
Description
Technical field
The present invention relates to medical treatment and nursing technical field, particularly a kind of Novel gastroscope trocar sheath and the application for gripping foreign body in esophagus thereof.
Background technology
Existing single channel gastroscope only allows single apparatus to pass through, and while needing to rinse, operating theater instruments must be withdrawn from from biopsy channel, and then saline injection etc. rinses the visual field in operation process, repeatedly changes apparatus, loses time, and also may miss operation good opportunity.Endoscopic Treatment becomes increasingly complex, and seance may need repeatedly to enter mirror, causes the very large misery of patient.
And existing dual pathways gastroscope is expensive, cost is higher, is unfavorable for popularization and application.
Bring sense of discomfort for avoiding repeatedly passing in and out gastroscope to patient, conventionally use gastroscope casing, an intubate, repeatedly passes in and out gastroscope through gastroscope casing, reduces patient's sense of discomfort.
Existing gastroscope casing, majority is tubular structure, and opening is set on casing wall, rinses affected part by casing wall water filling, makes to get a clear view.
And above-mentioned gastroscope casing is in flushing process, one side rinses strength and accuracy is not good enough, easily there is on the other hand the situation that flushing liquor overflows from entering Jing Kou, existing settling mode is, in the position at sleeve pipe middle part, air bag is set, a kind of gastroscope casing as disclosed in Chinese patent CN101066204A, airbag aeration is heaved and is stopped that flushing liquor or gastric content overflow.This kind of gastroscope casing complex structure, complex operation.
Summary of the invention
For overcoming the shortcoming of above-mentioned existing gastroscope, the invention provides a kind of that can immediately rinse, effectively prevent the gastroscope casing that gastric content overflows.
For achieving the above object, the present invention has adopted following technical scheme:
Gastroscope casing of the present invention, entirety is hollow tubular, and casing inner diameter is 1.1cm, and its inside and outside round decentraction forms the even sleeve pipe of wall unevenness, and heavy wall place thickness is 5mm, relative thin-walled place thickness is 3mm; In heavy wall place tube wall, irrigation channel is set, irrigation channel extends to outer sleeve bottom from the sidewall that enters Jing Kou end; The thin-walled place of closely entering Jing Kou arranges water injection pipe; Enter Jing Kou and irrigation channel entrance arranges silica gel plug, the lid of cross open centered by silica gel plug.
Further perfect as to such scheme, described irrigation channel diameter is set to 3mm.
Further, the opening of water injection pipe is general-purpose interface, can connecting tee, syringe or connection tube.
The invention still further relates to the application for gripping foreign body in esophagus by above-mentioned gastroscope casing, by trocar sheath and foreign body in esophagus close contact, make the strength transmission of gripping foreign body to trocar sheath, foreign body is out of shape or is broken, foreign body takes out in trocar sheath the most at last.
Use pliers gripping foreign body by the biopsy channel of gastroscope, avoid scratching esophageal mucosa.
Compared with prior art, the invention has the beneficial effects as follows:
1) trocar sheath, with irrigation channel, can be washed by water or send apparatus, the design of irrigation channel 3mm lesion, operating theater instruments that can delivery diameter 2.8mm, the trocar sheath of single structure had greater functionality more in the past, easy to use, more existing dual pathways gastroscope, with low cost.
2) trocar sheath is with irrigation channel, and the obstruction that can be used in inspection or therapeutic process in water filling flushing digestive tract exposes the body fluid in the visual field, keeps getting a clear view, and helps improve diagnosis capability.
3) when gastroscope need to repeatedly pass in and out bottleneck throat, trocar sheath is stayed in digestive tract, from trocar sheath turnover gastroscope, by an intubate, realized and repeatedly pass in and out gastroscope, reduced patient's sense of discomfort.
4) intubate, repeatedly passes in and out gastroscope, simple to operate, flexible, saves medical worker's workload.
5) trocar sheath length is set to 70cm, can arrive the darker gastric antrum place of patient's stomach, checks or operation technique, improves therapeutic effect.
6) enter Jing Kou and irrigation channel entrance and arrange the silica gel plug of central cross opening, stop gastric content, body fluid to flow out, save and clean the trouble of bringing, ensure operation seriality simultaneously.
7) on trocar sheath tube wall, water injection pipe is set, can water filling in trocar sheath, in the time entering mirror, resistance when reducing gastroscope and entering trocar sheath and between outer sleeve inner wall, make to insert mirror more smooth, the opening of water injection pipe is general-purpose interface, can connecting tee, the medical equipment such as syringe, connection tube.
8) design of irrigation channel is set in tube wall, can stop inward, easy to operate.
9) while blocking the foreign bodies such as fish spicule for patient's esophagus, it is most because foreign body lies across in esophagus, patient's taking-up foreign body of seeking medical advice, by trocar sheath and foreign body in esophagus close contact, makes the strength transmission of gripping foreign body to trocar sheath, foreign body is out of shape or is broken, foreign body takes out in trocar sheath the most at last, avoids foreign body directly to contact with esophagus inwall, scratching esophageal inwall, cause secondary injury, reduce patient's sense of discomfort and misery.
