Abstract
The utility model discloses a thoracoscope trocar. The thoracoscope trocar is formed by an inner layer and an outer layer, wherein a hollow cavity is formed between the inner layer and the outer layer, the upper end of the hollow cavity is provided with a negative pressure aspiration connector, the lower end of the hollow cavity is provided with a thoracic cavity connector, the outer layer is longer than the inner layer, the lower edge of the outer layer is connected with the lower edge of the inner layer through a concave sheet metal, and the concave sheet metal is provided with ventilating holes. A thoracoscope is not in contact with the outer edge of the trocar during a process that the thoracoscope enters into or is taken out from a thoracic cavity through the trocar, a lens of the thoracoscope can be prevented from being polluted during the process that the thoracoscope enters into or is taken out from the thoracic cavity through the trocar, the operation view is clear, negative pressure aspiration is generated as the negative pressure aspiration connector is connected with an aspirator pipe, smoke generated by burning, cutting, bleeding stopping and the like in the thoracic cavity can be sucked through the hollow cavity between the inner layer and the outer layer of the trocar and can be effectively discharged in time, the operation is convenient, the number of operation incisions is not increased, multiple purposes areachieved by one incision, and the operation efficiency is increased.
Description
Technical field
This utility model belongs to clinical device technical field, designs a kind ofly to prevent that thoracoscope camera lens is infected with and the stamp card of related suction pump.
Background technology
The thoracoscope stamp card of clinical practice is at present the cylindrical structural of monolayer hollow.In clinical position, due to otch limited amount, incision length is limited, can not hold more medical apparatus and instruments and operate.General thoracoscope otch is 3, each otch is respectively inserted a stamp card, one is entered thoracoscope, one is carried out the traction of histoorgan, one burn, cut, hemostasis etc. operate in carry out intrathoracicly burning, cut, in the process such as hemostasis, due to the restriction of stamp card structure, the flue gas that can not attract simultaneously, burn, produce in cutting, hemostasis, can not in time, effectively discharge outside thoracic cavity, affect the visual field, hinder operation.Block by stamp at thoracoscope on the other hand enter in thoracic cavity or taking-up process, stab card-edge often because of thoracic wall oozing of blood, touch the reasons such as lung tissue and often have hematocele or hydrops to be infected with thoracoscope camera lens, thereby affect surgical field of view, need to repeatedly take out stamp card and camera lens wiping, extend operating time.
In recent years, the colleagues that thoracic surgery is engaged in thoracoscope specialty have designed some novel stamp cards, such as the stamp card with suction pump, solve above-mentioned subproblem, but do not solve thoracoscope by stamp block enter in thoracic cavity or taking-up process, stab card-edge often because of thoracic wall oozing of blood, touch the reasons such as lung tissue and often have hematocele or hydrops to be infected with the problem of thoracoscope camera lens, therefore design an existing suction function can effectively prevent again thoracoscope block by stamp enter thoracic cavity or taking-up process in the stamp card be not infected with of camera lens just become a major issue urgently to be resolved hurrily.Based on this, we improve in the working practice that uses stamp card, be subject to fund project to subsidize (National Nature fund 30900585, National Nature fund 81100056, Shanxi Province basic research project 2011021038-2), designed a kind of utility model stamp card.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly prevents that thoracoscope camera lens is infected with and the stamp card of related suction pump, to overcome the deficiency of existing clinical device.
The technical scheme that this utility model adopts is: thoracoscope stamp card, the metal pipe structure that head and body two parts form, body tube wall is made up of internal layer and skin, between inside and outside layer, it is cavity, outer long compared with internal layer, outer lower edge is connected by concave metal ring with internal layer lower edge, porose on becket.Head tube wall has a transversal hollow metal pipe interface, and between the inside and outside layer of body, cavity communicates.
There are following innovation and advantage compared with the stamp card of design before: because body tube wall skin is long compared with internal layer, thereby when thoracoscope sticks into out thoracic cavity by stamp, camera lens can not contact outer lower edge and prevents that thoracic wall oozing of blood is infected with camera lens.
The beneficial effects of the utility model are, in operation process, head transversal hollow metal pipe interface connects aspirator tube and produces vacuum suction, by the cavity of body two interlayers, the flue gas that thoracic cavity endogenous cause of ill is burnt, cut, hemostasis etc. produces is attracted, discharge timely and effectively, easy to operate, and not increasing operative incision number, an otch has been accomplished multiple use; On the other hand because body tube wall skin is long compared with internal layer, can effectively prevent thoracoscope block by stamp enter thoracic cavity or taking-up process in camera lens be infected with, make surgical field of view clear, improve operation technique efficiency.
Accompanying drawing explanation
Fig. 1 is thoracoscope stamp card overall schematic: 1 stamp card chamber, 2 heads, 3 vacuum suction interfaces, 4 body outer walls, 5 inner layer tube walls, cavity between 6 ectonexines, 7 concave metal rings, the 8 upper holes of ring
Fig. 2 is the base map schematic diagram of thoracoscope stamp card.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and by reference to the accompanying drawings, this programme is set forth.
As shown in Figure 1, thoracoscope stamp card portion tube wall is made up of internal layer and skin, between inside and outside layer, is cavity, and outer long compared with internal layer, head tube wall has a transversal hollow metal pipe interface, and between the inside and outside layer of body, cavity communicates.As shown in Figure 2, outer lower edge is connected by concave metal ring with internal layer lower edge, and becket is provided with passage.Head transversal hollow metal pipe interface connects after vacuum suction by the cavity of the inside and outside interlayer of body, and the flue gas that thoracic cavity endogenous cause of ill is burnt, cut, hemostasis etc. produces is attracted; Because body tube wall skin is long compared with internal layer, thereby when thoracoscope sticks into out thoracic cavity by stamp, camera lens can not contact outer lower edge and prevents that thoracic wall oozing of blood is infected with camera lens.
Claims (3)
1. a thoracoscope stamp card, metal pipe structure, is divided into head and body, it is characterized in that: head tube wall has a transversal hollow metal pipe interface, and body tube wall is made up of internal layer and skin, outer long compared with internal layer.
2. a kind of thoracoscope stamp card according to claim 1, is characterized in that, between the inside and outside layer of body tube wall, is cavity, and outer long compared with internal layer, outer lower edge is connected by concave metal ring with internal layer lower edge, porose on becket.
